She is listed as being the mother of a William Carey but she no children by that name. I think that this persons (who would be my 12th great grandfather) name is really William Carey but that his parents are incorrect. I have tried to find a source that has the correct information but all the listings I have found so far either have this same information or have no parents listed. Anyone know how to fix this and to find the correct information for this person?
Very good catch - http://thepeerage.com/p2639.htm#i26388 does not list him as a child. I would start with FamilySearch.org as a possible originator of the record. Then I would go a generation or 2 down in the tree and look at the spouses. I don't think the issue is Cary / Carey / Carew variant spellings so much as a mixup / wishful thinking - Mary Boleyn was rumored to have has a child by Henry VIll. That rumor may also be the source of the record.
My little note, for what it's worth:
Her children Henry and Katherine might have been by her lover, King Henry VIII, rather than by her husband William Carey. [Anthony Hoskins, "Mary Boleyn's Carey children -- offspring of King Henry VIII?" in Genealogists' Magazine, Vol. 25 (March, 1997), No. 9, available at http://www.genealogymagazine.com/boleyn.html, visited 15 September 2007.]
Thanks to this profile giving us a hint and me being in school for genealogy plus needing a challenge, we have found out that Mary Boleyn is really my father's 13th great-grandmother. The hiccup is that it is through one of her first children that she is believed to have conceived with Henry VIII, they named him Henry. Read in many sources that when she gave birth to each of her first children Henry VIII gave tons of wealthy gifts to her father and husband. This will be a crazy headache to try to prove but as of now through DNA we have many of the surnames that are cousins all the way through. (Obviously not a confirmation until looked into with detail and added to my DNA-infused tree.)
