Help required on Michael Callahan please

[Cath19]

Hi,
Could someone advise me as to where I could find a work record on Michael Callahan, who, on the attached picture, states he was a fireman. The address he gave for the return of his passport was 21 Parker Street, Charlestown, and that was in 1922. I found a passenger listing of him returning from Queenstown ,Ireland to Boston, in Sept 1922 and the address he gave was his brothers, 9 Leon Street, Roxbury so I am a bit confused . I cannot find any trace of him after that so was hoping that if I could find a work record, it may give me a new lead. Any help & suggestions would be greatly appreciated. Thanks in anticipation!

Date of birth on the passport application is the same as this one - U.S., Social Security Applications and Claims Index, 1936-2007 - Michael Callahan - 20 September 1877 Republic of Ireland. Notes:   Jan 1937: Name listed as MICHAEL CALLAHAN. Parents - John Callahan and Mother: Elle Murphy

Hi Sandra, Yes you are correct and I don't seem to be able to find any information on that SSN number either. Drawing a few blanks!
Thank you

The first SSN was issued sometime in mid-November 1936 for the sole purpose of tracking the earnings histories of U.S. workers, for use in determining Social Security benefit entitlement and computing benefit levels.

It could mean Michael retired in that year and claimed some benefit - he would have been the right sort of age.

That would make sense, although in reality he had already 4 years knocked off his age as he was really born in 1873

Yes, that was very common back then
