There is a book The Geiger's of South Carolina by Percey Geiger, and it has information on the Heresy. Also I found info in a book by the Lutheran's I forget the name of the book right now. I live in Lexington,Sc in the area that was settled by the Geiger's. Abraham,Herman, John Conrad and Jacob. Some were Indian traders on the Congaree River. There was a Emily Geiger that was a spy in the Revolutionary War it seems she took a message to Sumter to the troops there. Also a John Geiger signed the succession from the Union in South Carolina. I am working in this same line, from Abraham and Mercey, my line is Abraham Harroll one of their children. Dm
