According to his U.S. WW 11 draft registration card that is listed on LDS Family Search website, his birth date is Dec. 25, 1888, and his place of birth is Douglas, Isle of man.

I think that IOM birth registration began in 1878, so, you may be able to order a copy of his 1888 birth record from the IOM Civil Registry Office. Here is their e-mail address- civil@registry.gov.im
