I would appreciate your sharing anything you might have on Teaford.
You mentioned that you thought Jacob might be Mary Ann (Anna) Teaford's father. Jacob supposedly had brothers Johan Heninrich (John?), Adam, Harrison, Elijah, and George -- all born in VA. George, John, & Jacob are the only ones I have seen records for in Darke County, OH, so I presume the others stayed in VA.
Do you have more on these early generations? What is your line?
Also, have you come across Wile/Weil in Jay County? My wife's descent from Mary Ann Teaford extends to a Jacob Weil/Wile who immigrated (possibly from the Alsace region along the France/Germany border) to Jay County sometime after 1833. The immigrant Jacob is said to have adopted the Wile spelling in America.
