I have a brick wall with a Wolf/Wolff/Wolfe line. Johann Carl/Charlie Wolff. I think he was from Germany. The Foust name is the same as the Vaudt name. My grandfather was a Albert Vaudt. The john carl wolf was my gggrandfather. Johann carl had a son in 1844 named John "Henry" wolf. Mother was Maria louisa "Charlotte" Eilbracht born 1818 in Germany. Lived in Monroe Co Illinois close to St Louis MO. Thanks for any help. Linda Spreen
