John "Futto" Biele (previously with the Genoveses) switched to the Patriarca Family in mid 1960s. Reasons unknown. But according to some FBI documents, Biele was not particulary popular with the Genovese bosses. I think they may have suspected him being an informant.
It also seems that most of the members in Bonanno´s west coast faction were allowed to switch membership to Families based in California after the Bananas War.
