Hi! I'm also researching these DeFelices. I have some pages of a memory book for my G-Grandfather's funeral (Frank Derbin). Nazireno DeFelice was a Pall Bearer. Mary DeFelice was in attendence.
Mary Defelice also attended the funeral of Anthony Derbin. Frank, Louis and Richard DeFelice were pall Bearers. They were also listed as honorary pall bearers.
Email me at firstname.lastname@example.org
and I'll send you photos of those papers. :)
Also, if you happen to have any info on the Piechocki side of the family it would be greatly appreciated!
Would you happen to know where Mary Ann Derbin fits into the family? I've become rather confused as to who her parents were.
