Seems like there are quite a bit of us DeMonaco roaming around eh? Well my name is James DeMonaco Jr. and I'm from California. I'd like to start working on a massive family tree and would appreciate your help and cooperation as much as possible, I could even send you a copy when complete :). So here is everything I know.
My father, James DeMonaco, has four brothers that I know of. John Thomas (lives in CA), Eugene "gino" (also lives in CA), Thomas "Tommy" (Lives in CA), and his other brother whom I can't recall meeting who lives in Canada now. All of them were born in New Castle and lived there until my grandfather moved her to CA. Their father (my grandfather) was John Thomas Demonaco. He had a brother named Al who was married to Minnie, they also lived in New Castle (Al passed away recently). John and Al's father (my great grandfather) was named Thomas. He is the brother of your Patsy, and they lived next door to each other in New Castle.
I just got off the phone with my father and he said that only a couple months ago he visited PA and actually visited Patsy and Lavinia's graves.
This is all quite a lot of work tracing back all these people, but It's something I've always wanted to do. I know these postings are all a couple years old but If you do see this, please write me back at Jamesdemonaco@gmail.com
