What you say makes complete sense...and of course they were Irish and not German. This is why I am hesitant to write to Churches. Is there a guide or something you can point me to that I can read up on these parishes that will help me make a more informed guess? I have performed google type searches but I must not be using the "right" keywords.
I have a LOT of family that came from Ward 5 (Navy, India, Java, West etc), all Irish or Irish-American and I have a feeling that finding the right Church will bulldoze a lot of those brick walls as they never registered with the city of Brooklyn and I assume it was only with the Church.
I tried to contact the Dioceses but they told me they were behind and asked me to contact them in a year. I did, three times, but then they never returned my emails. I wish they'd turn the records over to someone who would digitize and index them. I'd even pay for that subscription.
Interestingly, I think some parishes are getting ethnic again. My Parish, Our Lady of Perpetual Help, has masses in English, Spanish and Korean.
Thank you again for your reply. Very much appreciated.
