I'm not much help. The only information I show in my records is that the marriage was in 1830. Here is the burial information on Rachel from the Amerine Cemetery. Amerine, Rachel wife of Frederick 20 Jan 1827 32y-2m-28d.
According to the History of Union County Ohio: "Frederick, Jeremiah and Abraham, Jr., the three younger boys, removed with their families to the West. Frederick married Rachel Burris, and their children were Keziah, George, Amos. Maria, Nancy and James. His wife, Rachel, died in 1827, at the early age of thirty-two years."
The "West" was actually Iowa in Jeremiah's case. I have his brother, Jeremiah's bible records and there is no mentiion of Frederick at all. I do note that there is a large space in the cemetery next to Rachel Burris Amerine. I wonder if his other wife is buried there?
