General Notes

His wife's name was Mary B. (maiden name unknown). She was born about1879 in Ireland. She died on September 07 1965 in Wolcott, New Haven Co., Connecticut at age 95. Her last residence was in Bristol, Hartford Co., Connecticut.

(Alternatively, some records spell his first name "Irwin." His birth date might be September 24, 1870. A Lamoille County, Vermont birth record shows a male child, Levina Hadley, born September 24, 1870. There are no further records for any Levina Hadley in the family, and there is no birth record found with Erwin's name. Erwin's ages listed in the 1880, 1920, and 1930 censuses are compatible with a birth date of September 1870. Census records show Erwin, but no Levina, with his family of origin. It seems the birth record is probably Erwin's with an erroneous name listed. Erwin's death record shows his age at death as 80, which seems to be an error, since the 1880, 1920, and 1930 censuses are all consistent with his age. He was probably 81 years old at death.)
