Do you have the following LETTS listed in your bible and records?
Caroline LETTS born abt. 1825 in Woodstock, Canada, but her parents were American. Caroline married a William Heppel ROBINSON March 01, 1845 in Zorra, Oxford County, Ontario, Canada. They eventually moved to California. I believe that Caroline's parents MAY have been Jeremiah and Mahala (BAXTER) LETTS, POSSIBLY of the Pennsylvania or New York areas, although these locations are by no means verified at this point.
