I am contacting you about this profile: Gruffydd ap Cynan
I believe this is the same chap as in this Geni profile, with some of his ancestors skipping generations and so needs to be tightened up a bit. Gruffudd ap Cynan
Wikipedia has Gruffydd ap Cynan ap Iago ap Idwal ap Merig, but at first glance, not looking at archival sources, Wiki may have missed Elisedd generation, as in Idwal ap Elisedd ap Merig ? Thanks!
Martin, if you follow the lines you can see where (mostly) Steven and I have been working. Steven has been adding links to Darrell Wolcott's studies; I have been adding links to Peter Bartrum's notes, since the actual books are out of print.
The Welsh genealogy is extremely difficult, and the medieval manuscripts contradict each other.
Bartrum is the gold standard because he did the most to unravel and untangle the manuscripts; Wolcott has been working on the tangles that Bartrum didn't get to.
Question, does ap and ab mean the same thing, and is it always "son of" or can it be from the family of, as in ap Owain could mean Owain is a more famous grandfather to celebrate my lineage?
I've seen some listings that use ap and ab in the same thread, like Cynan ap Owain ab Gruffydd... and statements that some ap's list grandfather instead of the usual "son of". Wondering if this complicates things?
Ab and ap are the same thing; it's "ab" before a vowel.
They mean "son of." After the Welsh were legally required to use the English surname system (early 16th C), some of them used the "ap" construction, and simply carried it on. So after that, you see people using a surname like "ap Rhys," or "ap Rice," even though their father wasn't named Rhys. And certainly not Rice. And you see women using the construction too. (On the other hand, in rural areas, many Welsh families kept the patronymic system for centuries.)
But before 1500 (except for the families that married into the Marcher lords, or families that were city dwellers with a great deal of work with the English), it's patronymics. Ap fof son of and ferch or verch for daughter of.
"Cynan ab Owain ap Gruffudd" means "Cynan, the son of Owain, who was the son of Gruffudd," and is in no way confusing.
If anyone is using "ap" to mean "in the family of" or "grandson of," they are using it wrongly.
