I have a copy of the list. It was published in the Virginia Genealogist volume 31(1987), pp.40-47. Abraham and Dorcus are listed with children Amaus, Polley, Abraham and Eley Hubbard.
Other families include:

Day, McKey, Ball, Ashton, Locus, Davis, Massey, Cash, Williams, Sorell, Tate, Hammon, Washington, Mozingo, Taylor, Jones, Cannady, Johnson, Turner, Cary, Cooper, Harrison, Henry, Dixson, Gumby, Wells, Newman, smith, Gaskins, Newgent, Woodward, Weldon, Harris, Thomas, Glascock, Walker, Coleman, Wilson,Thornton, and Thompson.

Day, McKey, Locus, Mozingo, and possibly Ashton were free since colonial times. Quite a number of the families were the former slaves of Robert Carter of Nomony Hall who freed some 500 slaves by Westmoreland and Northumberland County deeds about 1791 to 1794.
