I was born in Robertsville, Ohio to Arthur and Gladys Clapper.
My grandmother was Lucinda Jane Blackledge (Clapper). Her father was James Franklin William Blackledge. Her grandmother was Jane Ann Deveaux (Blackledge). I know nothing but they came from France, and Jane Ann's father, John Francis Devaux and Joseph Robart purchased the property which became Robertsville. John Devaux had possession of the eastern part of the property, but later traded plus $ for the western end.
If you've heard of Ronald and Todd Blackledge, father and son football fame, they also came from Jane Ann's line.
I would enjoy any information.
