Thank you for the response. My Nelson Cain was born in 1804, both of the Nelson's that you found are in the 1930 period. Nelson & Catherine (Cretney) Cain had a daughter Rebecca born in 1929 and a Catherine in 1930. It is possible that one of the Nelson's that you mentioned might be a twin.

Thanks for your help. I have found 5 children so far, perhaps this may be another one.
