Had pretty much given up on this line.As you probably know, William married Sarah Mayse in 1836 (Bath Co. marriage bond)and you have the names of the children listed in the 1850 census.But I believe that this same William D. is also listed in the 1860 census in Bath County.The names and ages compare except for his wife who is listed as Sally (perhaps a nickname for Sarah).The record may be accessed through Heritage Quest--Series M653, Roll 1334, Page 265, surname spelled Swinegain.(This line has been exceedingly difficult to research using census records as the surname was often misspelled.)
I am descended from Charles, his eldest son.Charles was married in August 1859, to Barbara Ann Liptrap, daughter of Anthony and Sarah Liptrap (marriage bond).They are also listed in the 1860 census, page 291.Charles and Barbara had several children, among them a son named Charles W. (for William?), born 1864, died 1932, who married Julia Newcomer, daughter of William S. and Susan Saville Newcomer, August 1884.Their first born, a daughter, was my grandmother, Amanda.Charles and Julia had several children, mostly daughters.They married Loans, a Rusmisel, and a Phillips.Julia died, Charlesremarried, and had several more children.
If you would like any additional info, contact me via email.Although the copies of the marriage records are not of high quality, I'd be glad to share.
