I forgot to mention that there were two other sons of Frederick. Herbert 1873-? and John 1875. The last I could find Herbert he lived at Brass Castle which is near Washington, Warren, NJ and John lived in the New Village area. There are some Dittmar's related that now live in the Stewartsville area which is very close to New Village. Just don't have any death dates. A son of John's is John Russell known as Russell is buried at the Stewartsville Lutheran Cem 1907-1971. He has a son Richard.
