William Gaines of Culpeper Co., VA (died before July 18, 1796)
This man is sometimes referred to as William Henry Gaines. This is based on an incorrect reading of one court record. Calvin Sutherd discussed this matter in "The Gaines Family of Colonial Virginia and Their Descendants" and correctly determined that his name was simply William Gaines. I have seen abstracts or originals of all of the surviving court documents in which this William Gaines was mentioned and I agree with Mr. Sutherd in this case.
However, there are two other misconceptions that persist about this William Gaines. First, that he was a member of the House of Burgesses. This is unsupported by the records. There was a Harry/Henry Gaines who was a member of the House of Burgesses from King William Co., VA in 1758, 1759, and 1765-1767. However, the William Gaines who married Isabella Pendleton can be established to have been a resident of Culpeper Co., VA based on court records during at least part of that time period. Therefore, this William Gaines was a different man that the Harry/Henry Gaines of King William Co., VA.
Per Calvin Sutherd (GFCV, p. 406)
"From Henning Statute, Vol. I, page 23, he was a foot soldier in the Culpeper Militia in 1758."
This reference should be to Hening's Statutes, Vol. VII, p. 23 (The Statutes at Large; Being a Collection of the Laws of Virginia, from the First Session of the Legislature, in the Year 1619", Vol. VII, William Waller Hening), not volume I. The year was 1756, not 1758. The man listed as a foot soldier in the Culpeper Co., VA militia was a Henry Gaines, probably the son of this William Gaines.
