I am trying to trace the Callen family line. My grandfather was a Callen but took the name of his stepfather, i.e. Thompson. His father was Harvey Callen, born 1856 in Moravia, Iowa. His father was Prior L. Callen. I had information that the Callen Family Bible was with a Mrs Hays some where in Nebraska. Prior Callen's father could be an Edward Callen. I hope you can give me some leads.
