Conrad Ochs - Things I heard from the family

My father David Ochs was adopted by Erwin Ochs and his wife Pauline (Jensen) Ochs in 1944.
I remember visiting Eda and Ann Ochs who lived together in an upstairs apartment on Irwin Ave., Muskegon MI ~1972.
Erwin and Ferdinand had a falling out at some point, and were said to never have spoken again.
