From the Virginia Chancery Court records I found a lawsuit over the estate of Billington Williams, who died in 1786 in Amelia County, Virginia.
The court papers named Catherine as the widow of Billington Williams and said he left five children, Billington Jr. and daughters Jean Cabaniss, Anne, Mary and Elizabeth.
Here are two pages from the slim packet filed with the Chancery Court justices which contain family information.
Case 1791-007, Pages 4-5
