I am wondering what "Lea. worker" means when it's given as an occupation. I have seen it many times, but here is one example: https://familysearch.org/pal:/MM9.3.1/T ... c=14313855 (It is Image #290 in Family Search collection: Massachusetts, State Vital Records, 1841-1920: Births: Births 1919 vol 0136 Peabody-Petersham)
My only guess is that Lea. may be an abbreviation for leather.
