I had a family relative called Elias Friedland, who was a dentist, born in Russia in 1868 and came to USA in 1886. He married a lady called Rose, daughter of Simon Friedland. According to the 1930 census their son Sigmund born New York 1905 ish was married to a lady called Elizabeth. Your relative did not have any children. However it is possible that Elias Friedland the dentist might have remarried at some stage and not had any children in the next marriage. The last reference I have to him is his New York adress in my mum' 1933 address book. Do you think this is possibly the same dentist?
