Thanks so much !!
I pulled the probate record in Ancestry. It doesn't give any additional info except his wife's name. This Ambrogio on Blackwell St, definitely isn't my GGF as you stated. I had saved that record as a possibility. But this records clears that up. Mine died in NY in 1943.
However, the naturalization record in Barre doesn't state an address. So that may be a possibility still.
Interestingly, the death notice did mention the stonecutters union, which I never knew about. I did a little digging, and it seems the union didn't really archive records. But I will dig a little further.
There are were 5-6 granite/stone companies right on the block where he lived in Queens, NY. I saw them on old maps I pulled. Which I figured was why they lived there.
Thanks for your time and help !
