I will always remember you as a little girl working with your mother in the flower shop. Your father was my God Father. I always enjoyed the times I went to visit my cousins in South Boston, especially on St Patrick“s Day. I still remember our grand mother who loved so much to see her grand children.
Some of those memories are more than 70 years old.
Rest in Peace " My Cousin". Josie and Theresa are waiting for you.
