I have a reasonably good trace on this family line.William was the son of Leonard (b. 1773) and Nancy Ridgeway Vermillion.He was the fourth of four children that included Fielding, Katherine and Judson Vermillion. William's marriage to Mary McClain was his second marriage as he was previously married to Mary Ann Kidwell.William and Mary McClain had six children, with Charles being the eldest.William and Mary Ann Kidwell had one child, William Henry (b. 1840) and Mary Ann died shortly after childbirth.
