I am searching for information on John Acker. According to the 1820 census, there is a John Acker located in Woodberry Township, Huntington County, PA. U.S. land records show a John Acker of Huntington County, PA purchasing land in Delaware County, Indiana. This John Acker possibly had a daughter Margaret who was my wife's gg grandmother. Margaret, who died in Indiana, is known to have been born in Pennsylvania with a father named John. Any information that could confirm that this is the same John Acker, and that would provide additional details about him would be greatly appreciated.
