My husband is Michael Stephen Cassle. His father is Paul Emerson Cassle, your dad's brother.
We have done a genealogy of the family.My first posting at this site mentions George W. Cassle, born in 1820 (I posted it wrong originally).George's son was James Melton Cassle.James Melton's son was Jesse.
You probably have all this information from other researchers or family members.I have lots of names and dates if you are interested.
Mike and I have communicated with several cousins.We are in Modesto, CA.Where are you?Jean
