I must admit I have many, many cousins that I have lost track of there names or where they live. My mother *Mary DeFalco) was one of nine and each Aunt had at least two babies if not more. Those babies grew up (and that's where I've lost track) and had babies of there own . The names you have mentioned do not sound familiar to me now. I can see if I can find any of my cousins but it will take me some time. I don't know how quickly you need your answer.
How far back on the DeFalco side can you go? Does Frank, Frances, Lena, Patty, Madeline, Jean, Sal and Ann sound familiar. Those were my aunts and uncle.
