Ken:my records show Thomas Gary and Uriah Newman marrying ca. 1757 in VA.But, Thos Gary was mentioned first in SC, 27 Dec. 1754 whe he purchased from John Pitts 200 A. on Bush River.He also had a warrant for 100 a. on Saludy River and Bushy Fork, 6 June 1758.Thomas and Uriah were among the earliest members of Bush River Bapt. Church, and they are buried in a private cemetery on the original Thomas Gary home place, as recited by the sons, John, Newman and Samuel when they sold the original home place.The first child Nancy Eliz. Gary was born ca. 1759 in Newberry Co., SC.Possibly Thos purchased the first 200 a. before he married Uriah.I think you'd be safe saying they married between 1757 and 1759.
