Thomas Martin - Thomas Martin birth date unknown

Thomas Martin(s)b.unknown married Susan/Susannah Walker 23 or 27 Oct 1772 Goochland,Virginia.
Due to receiving a FFDNA match with the above Thomas Martin(s) .The person who matched me has a Brazilian/Azores/Spain familytree right back to 1400s.Anybody here adversed with this Thomas Martin(s) as I can find nothing other than his marriage date and the birth of 3 children all registered for birth in Goochland,Virginia. Being Elizabeth Betsey Martin born 1774 who married David Jesse Bowles(my 3rd great grandparents)Dabney Amos Martin and William Martin.Like to hear any advice in discussions.Thank you, Pat Rodgers.
