Northaven

I am looking for a man who was adopted in late 1959. He was adopted through Northaven in rochester, ny. If he knows his birth parents last names they are darling and shaffer. Unsure of his dad signed the adoption papers. He does not know he also has a daughter that was also placed for adoption. The adoption papers were signed by his daughters mothers husband. Her birth mother won't tell her his name. (He is 14 years younger than bms husband). His daughter found out about him due to ancestry dna testing and matching with his mother. His birth family as well as her are looking for him.
