Thanks again for the information. I have not emailed the Brooklyn Library. Will do so. Do not know John's wife's name. Thomas never married.

Could not find O'Neils Funeral Home listed in the NYS Funeral Directors web site.

Do know that John and Thomas are buried in a family plot in Holy Cross

Have you tried Google News? Archives are now online. The aticles must be purchased but the cost is low.
I found my great grandfather's probate info there.
Just go to Google News-type in what you want (I typed in 7106 Ft. Hamilton Brooklyn) anf then to the left of the screen, selected all dates and an awful lot of obits came up from the funeral home you are looking for.
Hope this helps.
P.S.
I didn't read all your previous posts but if you are looking for info on people of Irish ancestry, the Irish Parishes around Ft. Hamilton Parkway are
Our Lady of Angels on 4th Avenue Brooklyn (11209)
St. Patrick's 5th Avenue (11209)

St. Ephrem tended to be more of an Italian Parish.
St. Anselm's was a bit of everything 4th Avenue (11209)
A very large Irish congregation worshipped at Our Lady of Perpetual Help on 5th Avenue and 60th Street.

Another P.S.
I am not sure where you live but I live within a holler of 71st Street and Ft. Hamilton Pkwy.
I believe the spot is now either an apt building or a furniture store (I will have to take a walk over there to check it out).
If there is anything I can do for you from my place in Brooklyn -just let me know. So many people around the country assisted me when I was searching.
Best regards,
Madeleine

I googled the address, and got this:

Ft Hamilton Mkt
7106 Ft Hamilton Pkwy,
Brooklyn, NY 11228
(718) 238-7622

Maybe the current owners will know the history of the building.

Hi Madeline
Read your postings. Thanks for the information and your offer to help, My family lived in the Bay Ridge section of Brooklyn. I went to grammer school at OLPH, than moved to LI. Still there.

Hi Pat
Thanks for answering my query and sending the information

Dan.

Sorry, I thought you might have been far away and generations removed.
I live in Bay Ridge and so, if I can do anything for you, as I live here, just let me know.
Anything I can do for a fellow Bay Ridger-I will be happy to do.
Very best regards from Bay Ridge

Dan, I did a search on the Brooklyn Information Page on "O'Neil"...came up with an obituary that mentioned
..."Interment
will be at Calvary Cemetery under direction of John O'Neil, 334 Court street." I googled funeral homes in that area, and there are several (no O'Neil's though), but the closest is Raccuglia's at
323 Court St, Brooklyn, NY
(718) 855-7737

I've been to services there, so I know they are very much in operation. Hope this helps.
