I have first found Thomas Boatwright in 1733 in Henrico County, Virginia. He purchased 322 acres on the Tuckahoe Creek for 1.515 Pounds. At this time it appears his neighbors are Richard Wade and Nicholas Cox. In 1735 a Mr. John Watson received land on the North Side of James River adjacent to Thomas Boatright. Also mentioned in New Kent County is an Elizabeth Boateright and John Boatwright. (Cavaliers and Poneers, Abstracts of VA Land Patents and Grants, Vol IV, pg 10)
Although it is not conclusive that Thomas is the father of Daniel it appears logical. He may ahve also had a son named James.
In reference to Thomas Boatright I have found the following:Cavaliers & Pioneers, Abstracts of VA Land Patents and Grants, Vol IV, 1732-1741. VA Genealogical Society, edited by Denis Hudgins on page 3 and 81.
