My Cox line is Mathew, Jared Rollins and Elizabeth Amanda Cox. She married Jasper McManus and their daughter Loa is my grandmother.
One of my cousins (Bob Flygare) did a lot of research on the Biggs line.
Another cousin passed on Williams letter to his brother Ben after returning from his capture.
i visited the Madison Co. hist. Soc. in Edwardsville a few years ago and copied quite a bit of info,including the story of his capture. I had been looking for it for some time and it made my day. Quite a story.
