Still Searching- Half Brother 1973 Catholic Charities

Iso half brother born in 1973 in New York sometime I think before Easter or right around easter. Catholic charities handled the adoption and he was born in or around the Albany area. Either at Albany Hospital or St. Peters hospital ( I think thats the name) He as adopted before she even gave birth so the new parents were there at time of delivery. If any of this sounds familiar please let me know! I am feeling a bit discouraged, for I have been searching on and off for around 9 years now. Anyways, thank you again. My Mother was put in one of those Catholic Charities Homes or a Pregnancy Home during her pregnancy. Her parents put her in their after they found out she was pregnant. She stayed there with other young pregnant women until she gave birth. Her name is Elizabeth. I appreciate any input or advice too! Have a wonderful day!
