Find-a-Grave is like any other site, only as correct as the information the individual enters. I find errors and omissions on Find-a-Grave profiles all the time. Not everyone even attempts to document the information they post there. So, it's always best to compare what is on there to other sources that have documentation when there is none on that site. Same with Geni, or any site really. I tend to favor Wikipedia when it is well-sourced but have even found errors on there.
All that said, I Googled Ivo with the plan of working from him down to Beatrix and what I ran into was this:
https://en.wikipedia.org/wiki/Ivo_Taillebois
"Ivo's only known heiress was Beatrix...It is not certain whether Beatrix was a daughter of Lucy, and it is also not certain what connection Beatrix or any other relatives might have had to later Taillebois families...There has been much speculation and discussion about Lucy, and even whether she was one person."
So, it appears that it's not proven that Beatrix was Lucy's daughter or exactly who Beatrix's mother was. Gundreda isn't even mentioned in the discussion.
Based on this, I'd suggest Beatrix be attached as a daughter of Ivo and her mother left unnamed altogether unless someone has actual documentation.
Well, Medlands seems to indicate that a certain "Lucy" was the wife & mother of Beatrix:

IVO Taillebois [I] (-[1094/95], bur Spalding). Ragg lists property in Lancashire and Westmorland which Ivo [I] donated to York St. Mary but does not cite his sources[3]. "…Ivo Taillebois, Robert de Oilli" witnessed the spurious charter, purportedly dated 25 Dec [1071/75], under which William I King of England donated Chelsea to the monks of Westminster[4]. "…Ivonem Taillebois…" witnessed the charter under which William I King of England confirmed the rights of Ely abbey[5]. “Ivo Taleboys” donated Spalding Monastery to the church of Saint-Nicholas Anjou, for “conjugis suæ Luciæ et antecessorum Toraldi…uxoris eius” by undated charter[6]. “Ivo Talliebois” donated property to St Mary, York, for the soul of “uxoris meæ Luciæ”, by undated charter witnessed by “Lucia uxore mea, Ribaldo genero meo, Radulpho Taillebois…”[7]. A charter of King Henry II records donations to York St Mary, including the donation of land “in Claxtuna et ecclesiam de Kirkby-Stephen…” by “Ivo Taillebois”[8]. Domesday Book records “Ivo Taillebois” holding numerous properties in Lincolnshire[9]. “…Ivonis de Taliber…” witnessed the charter dated Sep 1093 under which William II King of England donated property to Lincoln cathedral[10]. Ingulph's Chronicle of the Abbey of Croyland records the death of "Ivo Taillebois who had always been a most bitter enemy to Croyland" and his burial by "his wife the lady Lucia" in the priory of Spalding[11]. m as her first husband, LUCY, daughter of --- (-1138, bur Spalding). The Chronicon Angliæ Petriburgense records "Luciæ comitissæ…filiæ Algari comitis Leicestriæ" as husband of "Ivo Tailbois comes Andegavensis, dominus Spaldingiæ et totius Hollandiæ" and "Toraldus avunculus eiusdem Luciæ"[12]. No other source has been yet been identified which names one of the parents of Lucy. If the source is accurate (and it is a later source), it is not known whether the relationship with Thorold was through Lucy’s father or mother, although if "avunculus" is used in its strict sense (which is not beyond doubt) Thorold was her maternal uncle. A manuscript recording the foundation of Spalding monastery records that “Yvo Talboys” married "Thoroldo…hærede Lucia" who, after the death of Ivo, married (in turn) "Rogerum filium Geroldi" and "comitem Cestriæ Ranulphum"[13]. “Ivo Taleboys” donated Spalding Monastery to the church of Saint-Nicholas Anjou, for “conjugis suæ Luciæ et antecessorum Toraldi…uxoris eius” by undated charter[14]. She married secondly (after 1094) Roger FitzGerold. Ingulph's Chronicle of the Abbey of Croyland records that "his wife the lady Lucia" married "Roger de Romar the son of Gerald de Romar" when "hardly had one month elapsed after the death" of her first husband "Ivo Taillebois"[15]. She married thirdly (1098) Ranulf "Meschin" Vicomte du Bessin. Ivo [I] & [his wife] had [two] children:
a) [[BEATRIX] . Assuming that “genero” in the following document was used in its strict sense of son-in-law, Ribald’s wife was Ivo’s daughter: “Ivo Talliebois” donated property to St Mary, York, for the soul of “uxoris meæ Luciæ”, by undated charter witnessed by “Lucia uxore mea, Ribaldo genero meo, Radulpho Taillebois…”[16]. The difficulty is that “gener” was sometimes used in medieval documents to indicate brother-in-law. Ingulph's Chronicle of the Abbey of Croyland records that the "only daughter" of "Ivo Taillebois…[and] his wife the lady Lucia" married "a husband of noble rank" but "died before her father"[17]. It is possible that this passage refers to the wife of Ribald. Assuming that this was the same wife of Ribald, her name is confirmed by the following document: “Ribaldus frater comitis” donated property to St Mary, York, for the soul of “Alani comitis et Beatricis uxoris meæ”, by undated charter[18]. As Ingulph says that Ivo’s daughter predeceased her father, it is possible that Beatrix was a later wife of Ribald and not Ivo’s daughter. m RIBALD, illegitimate son of EUDES de Bretagne Comte de Penthièvre & his mistress ---.]
b) [daughter . Domesday Descendants suggests that Ingulph (quoted above) was incorrect and that Ivo Taillebois [I] left a second daughter who was the wife of Eldred, noting that the couple’s grandson William de Lancaster held the barony of Kendal which Ivo had previously held[19]. This is contradicted by an undated manuscript relating to Cockersand Abbey, Lancashire which names “Elthredum” as son of ”Ivo Tailbot”[20], although this statement is improbable as no other primary sources indicate that Ivo had sons. m ELDRED, son of ---.]
https://fmg.ac/Projects/MedLands/enguntlo.htm#LucyM3RanulfChester
a) THOROLD de Bukenhale (-after [1076/79]). Sheriff of Lincolnshire. The Annals of Peterborough record that “Thoroldus vicecomes et frater germanus Godivæ comitissæ Leycestriæ” founded Spalding Monastery in 1052[875]. “Thoroldus de Bukenhale…vicecomiti” donated Spalding monastery to Croyland abbey which names “domino meo Leofrico comite Leicestriæ et…comitissa sua domina Godiva sorore mea…et cognati mei comitis Algari primogeniti et hæredis eorum”[876]. Herman’s De miraculis sancti Eadmundi names “…Lincolniensis Turoldus…” among those present when Herfast Bishop of Thetford visited Baldwin Abbot of St Edmund’s to be cured of an injury to his eye, dated to [1076/79] by Round[877].
b) GODGIFU (-after [1054/57]). She is named as wife of Earl Leofric by Florence of Worcester, who specifies that she and her husband founded monasteries at Leominster, Wenlock, Chester and Stowe[878]. The Annals of Peterborough record that “Thoroldus vicecomes et frater germanus Godivæ comitissæ Leycestriæ” founded Spalding Monastery in 1052[879]. Her family origin is also indicated by the undated charter under which “Thoroldus de Bukenhale…vicecomiti” donated Spalding monastery to Croyland abbey which names “domino meo Leofrico comite Leicestriæ et…comitissa sua domina Godiva sorore mea…et cognati mei comitis Algari primogeniti et hæredis eorum”[880]. The De Gestis Herwardi Saxonis names "Aediva trinepta Oslaci ducis" as wife of "Lefricus de Brunne, nepos comitis Radulfi cognominati Scalre", when recording that they were parents of "Herwardus"[881]. "Oslaci ducis" could be "Oslac" recorded in the Anglo-Saxon Chronicle as "earl [of Northumbria]" in 966[882], but any precise relationship has not been identified. ”Leofricus comes…et conjux mea Godgyve” donated property to Evesham Monastery by undated charter which names “frater meus Normannus”[883]. Godgifu wife of Leofric granted property to St Mary's, Stow by charter dated [1054/57][884]. Orderic Vitalis records that “Elfgarus comes” had founded “Coventrense cœnobium” and that “Godiova...comitissa” donated “omnem thesaurum suum” to the church[885]. She was the Lady Godiva of legend. m LEOFRIC Earl of Mercia, son of LEOFWINE Ealdorman of the Hwicce in Mercia (-Bromley 30 Oct 1057, bur Coventry).
c) [daughter . The source quoted below which names Thorold as "avunculus" of Lucy suggests that he was her maternal uncle, assuming that the word was used in its strict sense (which is not without doubt). m ---. It is unlikely that the sources quoted below, which name Lucy as daughter of "Algari comitis Leicestriæ", are reliable. It is assumed that they all refer to Ælfgar Earl of Mercia (see ANGLO-SAXON NOBILITY), which would mean that Lucy was the sister of Earls Edwin and Morcar. However, such a relationship appears chronologically impossible, even if Lucy was born very late in the life of Earl Ælfgar (whose death is dated to 1062), considering that she apparently had four children by her third husband whom she married in 1098.] One child:
i) LUCY (-1138, bur Spalding). According to a charter of Henri Duke of Normandy (later Henry II King of England) issued in favour of her son Ranulf Earl of Chester dated 1153, Ctss Lucy was the niece of Robert [I] Malet of Eye and of Alan of Lincoln: "H. dux Norm. et comes And." granted land to "Ranulfo comiti Cestrie", including "totum honorem de Eia sicut Robertus Malet avunculus matris sue" had held and "foeudum Alani de Lincol…qui fuit avunculus matris sue", by charter dated to [Jan/Apr] 1153[886]. The precise relationships between all these individuals has not yet been ascertained. Domesday Descendants suggests that Thorold was her father[887]. Keats-Rohan expands her arguments in another article, based primarily on the presence of both Thorold and his wife as "antecessores" of Lucy and her first husband in the charter under which the couple donated Spalding monastery to the church of Saint-Nicholas, Anjou (see below)[888]. The Complete Peerage also discusses whether Thorold could have been Lucy’s father and that her mother could have been the daughter of Guillaume [I] Malet[889]. An alternative origin is suggested by Ingulph's potentially spurious Chronicle of the Abbey of Croyland, which records that William I King of England arranged the marriage of "Ivo Taillebois" and "Lucia sister of Edwin and Morcar", her dowry consisting of their land at Hoyland[890]. The Genealogia Fundatoris of Coventry Monastery also names “Luciam postea comitissam” as daughter of “Algarus tertius”, adding that she married firstly “Yvoni Taylboys” by whom she was childless, secondly “Rogero filio Geroldi Romara”, thirdly “Ranulfo comiti Cestriæ”, and that she was buried “apud Spalding”[891]. The Chronicon Angliæ Petriburgense records "Luciæ comitissæ…filiæ Algari comitis Leicestriæ" as husband of "Ivo Tailbois comes Andegavensis, dominus Spaldingiæ et totius Hollandiæ" and "Toraldus avunculus eiusdem Luciæ"[892]. Lastly, the Annals of Peterborough name “Yvo Taylboys, comes Andegavensis, dominus Spaldynge et totius Holandiæ…maritus Luciæ, filiæ Algari comitis Leicestriæ” and "Toraldus avunculus…Luciæ" when recording his donation to Spalding Monastery in 1074[893]. This relationship with Earls Edwin and Morcar appears impossible from a chronological point of view, in particular because Lucy gave birth to children by her third husband at a time when she would have been over fifty if she has been their sister. It also seems unlikely that their sister would have been given a name derived from the Romance languages. “Ivo Taleboys” donated Spalding Monastery to the church of Saint-Nicholas Anjou, for “conjugis suæ Luciæ et antecessorum Toraldi, scilicet uxoris eius, requie” by undated charter[894]. Peter of Blois's Continuation of the Chronicle of the Abbey of Croyland records the death of Ivo and his burial at the priory of Spalding, and the remarriage of his widow "hardly had one month elapsed after his death" with "Roger de Romar the son Gerald de Romar"[895]. A manuscript recording the foundation of Spalding monastery records that “Yvo Talboys” married "Thoroldo…hærede Lucia" who, after the death of Ivo, married (in turn) "Rogerum filium Geroldi" and "comitem Cestriæ Ranulphum"[896]. Ingulph's Chronicle of the Abbey of Croyland records that "his wife the lady Lucia" married "Roger de Romar the son of Gerald de Romar" when "hardly had one month elapsed after the death" of her first husband "Ivo Taillebois"[897]. She is named as wife of Ranulf by Orderic Vitalis, who also names her first husband, but does not state her origin[898]. “Ranulfus Meschinus Richerio Vicecomiti Karlioli” donated property for the foundation of Wetherhal priory, Cumberland, for the souls of “…mea et uxoris meæ Luciæ…”, by undated charter[899]. The 1130 Pipe Roll records "Lucia comitissa Cestr…tra patis sui" in Lincolnshire[900]. “Lucia cometissa” donated “manerium de Spallingis...cum quibus melius tenui et liberalius tempore Ivonis de Thallebos et Rogeri filii Geroldi et cometis Rannulfi” by charter dated to [1135][901]. m firstly IVO Taillebois [I] Lord of Kendal, son of --- (-after 1094, bur Spalding). “Ivo Talliebois” donated property to St Mary, York, for the soul of “uxoris meæ Luciæ”, by undated charter witnessed by “Lucia uxore mea, Ribaldo genero meo, Radulpho Taillebois…”[902]. m secondly (after 1094) ROGER FitzGerold, son of GEROLD "Miles Christi" Châtelain de Neufmarché & his wife Aubreye (-[1096/98]). m thirdly (1098) RANULF "Meschin" Vicomte du Bessin, son of RANULF Vicomte du Bessin [Bayeux] & his wife Marguerite [Maud] d'Avranches (-17 or 27 Jan 1129, bur Chester, Abbey of St Werburgh). He was appointed Vicomte d'Avranches in 1120 and Earl of Chester.
Marvin Loyd Welborn, nice to meet another cousin. :)
Well, that seems to concur with the exclusion of Gundreda as Beatrix's mother, which makes the current Geni connection in correct. If I read all that (and there's a lot of it - lol) correctly, it's saying Ivo was buried by his wife Lucia / Lucy. Everything indicates her parentage is unknown but definitely has her first name.
At least this portion about Beatrix from what you shared above mentions Lucia / Lucy and Ivo as Beatrix's parents:
[[BEATRIX] . Assuming that “genero” in the following document was used in its strict sense of son-in-law, Ribald’s wife was Ivo’s daughter: “Ivo Talliebois” donated property to St Mary, York, for the soul of “uxoris meæ Luciæ”, by undated charter witnessed by “Lucia uxore mea, Ribaldo genero meo, Radulpho Taillebois…”[16]. The difficulty is that “gener” was sometimes used in medieval documents to indicate brother-in-law. Ingulph's Chronicle of the Abbey of Croyland records that the "only daughter" of "Ivo Taillebois…[and] his wife the lady Lucia" married "a husband of noble rank" but "died before her father"[17]. It is possible that this passage refers to the wife of Ribald. Assuming that this was the same wife of Ribald, her name is confirmed by the following document: “Ribaldus frater comitis” donated property to St Mary, York, for the soul of “Alani comitis et Beatricis uxoris meæ”, by undated charter[18]. As Ingulph says that Ivo’s daughter predeceased her father, it is possible that Beatrix was a later wife of Ribald and not Ivo’s daughter. m RIBALD, illegitimate son of EUDES de Bretagne Comte de Penthièvre & his mistress ---.]
Based on what you've presented, I'd say her mother needs to be corrected. Thanks for all you put into clearing this up. :)

One thing you have to watch out for with MedLands is Cawley's bad habit of severely abbreviating his quotations from his sources. This can make it *very* hard to tell whether, for instance, someone is donating property for prayers for the soul of a deceased spouse, or more generally for the spiritual welfare of said spouse. (Got singed that way once, have been alert for it ever since.)
