James Francis is his name from his baptismal record, although
he's named Frances J. Monahan in the 1910 census and Francis in 1920.
His death is only from an SSDI record with a matching birthdate, SSN
issued in Illinois, name James Monahan.
Likewise, I can't confirm it was this James Francis Monahan who married
Esther, but I believe so (his full name is given in the marriage record).
