Am I right in thinking this is your Elmer Samuel Bassett ? He must have married twice. If it is the right Elmer have you check where his parents were born.

Did Elmer leave the USA at any time to say Canada or England. When was the Certificate of Naturalization issued. Have you checked for entry into the USA. The only thing I can think is he could not prove he was already a USA national. Could he have applied for the Certificate to prove who he was ie like a passort to leave the USA.

This looks like the family in 187o and Elmer.

Going back to the Certificate of Naturalization if the family went outside the USA was the cert for a child born while out of the country.

Yes, my GGrandfather was married twice. His first wife Ester Metcald and his second wife was Ila Berthenia Lukenbill. He did live in Canada and both him and his father had some land. They did not got to England and as far as I know there were no children born outside of the United States.
Thank you for your information and response.
