Michael DeLorenzo may be the son of Arthur Delorenzo, Uncle Ted's brother who lived in NY City. Arthur is deceased. Arthurs's wife was/is Carmen, I think. She may still be living. I met them once. My sister says they had children. Arthur's wife's family was originally from Puerto Rico, if I recall correctly. It was a long time ago. There are probably a hoard of other DeLorenzo cousins there if the opera musician had a large family. Michael is a pretty popular name among Italian Americans. He could be related via the great-grandfather's brother. Stage names are also often adopted from mother's maiden names, so he could be related via a great-great aunt from the De Lorenzo line. That part remains a mystery for now. Vicky is my first cousin via Ted's first wife, Irma. He remarried after she died. I know the history, but not all of it. If you can contact Eugene he may be a better source. As far as I know he and his wife are still living. Eugene has three daughters who may have some contact with your NY cousins. Eugena (Eugenia?) Theodora, and Christina.
