It appears that James the V had a Liasione with a woman, not his wife and the child born was Mary Stewart who's subsequent marriage to Thomas Grey of Butterfaulk leads to Patric Grey married the Tudor Descendent, Jane Tudor-Grey. Their Daughter also named Jane carries the name MERCER....and there is no mention of this family on either the family of Jane or her Daugher Jane Mercer-Wilkinson.....who connectis to the CROMWELL family...Descended from TACINDA TUDOR.....I am looking for help, guidance tracking William Mercer, father of Margaret MERCER who is my 9th great grandmother. She married the very well known and tracked great grandson of Sir Rhys ap Thomas 1449 of Bosworth Fame: Thomas ap Rice 1570 son of John ap Rice II and Katherine Perrott of Goggerdan, Wales. The above is the best I can do at this point....The Geni machine does not track this family (MERCERS) for me to see the connection....I did see the Tudor Era Mercer House in Tenby, now operated as a Musieum.....but that's all that I can find on the internet as well as physical search for the family....PLEASE ADVISE.
