Hi Jaxmum,
Reply 2 on the original thread gave a couple of suggestions for contacts re obituary - did you ever try to go down those lines ?
Spent a little time going through the SSDI, looking for the death record for Lily and cannot see anything under Beard - not sure if anyone else has looked. Beginning to wonder if Lilly could have married again after the death of Elmer, she would only have been 49 years old.
Clutching at straws but started looking for any Lilly born 1913 and who died 1987 in Indiana - could this be a possibility I wonder - Lilys birth was registered last quarter of 1913 in the UK

Lily Ewing
Born 22 September 1913 and died February 1987
Last Residence: 47150 New Albany, Floyd, Indiana,
SSN was issued in Indiana (Before 1951)
