Jim, I don't know anything more about Daniel Brown than I pieced together from census records, but I offer the following: You listed five children under Angeline Brown and "Simeon Calihan". Mahala Angeline Brown was Simon P. Callihan's second wife. Oliver P. and Ella were Angeline's children with Simon. Regarding Frederick versus Frank P: we can reasonably conclude that was the same child. Perfection in census records is hard to come by. Collect as many records as you can find, make a best guess, say "maybe" a lot. My work includes working with families who lived in Fountain Green and Hancock Townships.
