I seldom look at this website. To respond to you: David Parrish b c 1715 VA did have a wife named Judith but her maiden name is unknown.
This David's nephew, David Parrish b c 1730 Goochland Co VA did marry Judith Holland in Jan 1758 per the Douglas Register. The only child that I know that they had was Martha Holland Parrish b Dec 1858 Goochland Co VA.Martha married James Cocke, Jr.
I am descended from David Parrish b c 1715.He moved his family to Granville Co NC about 1753.He died there in Aug 1792.His will named his children: David, Jr, Clayton, Booker (deceased when will was written in Aug 1789), Suki (Susannah), Tabita (my line), Ann, Betsy, Judith, Sarah. He also had a son named John, who was the eldest son. It is assumed that he had provided for John when they removed to Granville Co NC.Any other children you have were not his. I have thoroughly researched this line.
