Disputed Descendants
Sir Francis Bryan had at least one illegitimate son "who is mentioned as carrying a despatch to London in 1548 from the French admiral"[1] - by Abigail Elwell?[8] He had no known legitimate children who had issue, although online trees give him a son by Philippa as well as Francis by Joan. Tudor Place gives him three children: Edmund by Philippa, Francis and Elizabeth by Joan.
This online tree (unsourced) says that Philippa's granddaughter, Anne Butler Bryan, married Gen. Spottswood. However, "Colonel Spotswood married, in 1724, Ann Butler Brain, daughter of Mr. Richard Brain, of London".[9] Wikipedia has his wife's name as Anne Butler Brayne.
Richardson does not show that Sir Francis had any children by either of his wives (but also does not note "no issue" by either).
At his death, Sir Francis and his wife, Lady Joan Fitzgerald, had a son, Francis, but historians do not have evidence he lived beyond early childhood.
Nevertheless, many people (including me in years past) have claimed Sir Francis as an ancestor. See this site: Tudor History blog.
I use the Rootsweb free Medieval genealogy list for the latest research, done by others, since I have no access to original records, on any connection back to English history. I also own the book The Spear and the Spindle about the ancestry of Francis Bryan, son of Sir Francis and Lady Joan (see below).
The Name and Family of Bryan or Brian by Thomas R. Bryan (p. ix) states that Sir Francis Bryan had issue of a son named Francis by his second wife.... The young Francis Bryan held lands in the County of Clare, Ireland; married an Ann Smith, and had a son William or William Smith Bryan who was deported in 1650 by Cromwell. "
Where is documentary evidence for this?

Paul Gifford posted this at Genforum: From this source, J. D. Bryan, "The Boone-Bryan History," an article in the_Register of the Kentucky Historical Society_ 3, no. 9 (Sept. 1905), and reprinted as a booklet in 1913, writes that Morgan's father was "believed to be William" Bryan and that his mother was "believed to be Sarah Bringer."
Then J. W. Shearer, in _The Shearer-Akers Family_ (Somerville, NJ, 1915), who was interested in the descendants of William Bryan, who, according to a documents passed down through his descendants, had been of Ballyroney, Ireland, in 1717, made this William Bryan out to be Morgan Bryan's brother. He changed the name of the father to "William Smith Bryan" and had him coming to Virginia in 1650. There is, of course, no documentation here.
Later versions changed William to Francis Bryan and made "Bringer" into "Brinker" and had her Dutch and related to the Prince of Orange (I wonder if the story "Hans Brinker" by H. C. Andersen had appeared sometime in the meantime and influenced this). What were guesses in 1905 became, by 1934 or 1946 (Edward Bryan, "The Bryan Lineage and Alliances, Filson Club History Quarterly, 20 [1946]: 37-8) facts, at least as far as Morgan Bryan's ancestors are concerned.

So an invented son Francis ll (or a mixup of real persons, a died young son & an unrelated landowner in County Clare) leads to a fabricated “William Smith Bryan” marrying an imaginary Dutch noble woman in order to produce Morgan Bryan of North Carolina and a Royal Pedigree for Daniel Boone descendants.
Does that sound about right ?
