There was an old genealogy printed that said a John Martin 1685-1756 had married a Letitia Lewis. It then connects lots of issue to them. It also says he was a Burgess.I can't tell you about Letitia Lewis. BUT the John Martin who was a Burgess for King William CO and died in 1756 did leave a will wrote 5 October 1748.It is in the Waller family papers acc #26035.His wife was a Elizabeth. He had issue: William Peters Martin born 1 June 1745, George, James and Alice Martin.All of these children were born 1734-1745. His will tells you some are under 16.Also names a sister Agnes Cunningham. This John is the son of James Martin of Ireland.Also a nephew to Col. John Martin who also died in Ireland in 1760. This John got a title of Col. also from military service for the colony. Dr. George Martin of Dublin also wrote a will July 1746 and mentioned his brother James Martin's issue: Agnes Cunningham a widow, John Martin and Letitia Thomas. Dr. George, Col John, James Martin and Letitia Martin Campbell were all brother and sister.
