Just found out that we had a cousin Fanny (or Fannie) who married a Mike (Mendal or Mendel) Halpern and had a son named Ralph.
A cousin told me that she met them and that they settled in California. Her grandfather and my great grandfather were brothers. Her grandfather went to the west coast and that was the last my family had heard about his family until I found her and she has helped me with some of the missing pieces from that part of the family. My great grandfather was Shmuel Buchalter and her grandfather was Samuel Bear (formerly Shlomo Buchalter)
Now, between us, we are trying to find the information on the Halpern family and how exactly Fanny is related to us. We suspect that one of her parents' was married twice and that she is a half-sister to my great grandfather and her grandfather.
