Interesting. Amy, I have not seen your GED file. I already knew of the marriages between the Cains and Stevens family. Part of my information comes from my research into Fredric or Frederick Fuller Stevens, and his father Isaac Stevens, son of William and Polly Morgan Stevens. There is a book that addresses Isaac's father in law, Fredric Eherman. There is another book that covers others in William and Polly's family, primaily the brohters who moved to Grant County. I have not seen or found a copy of this book however some of the information can be found at Bill and Cindy Cupps web site.
