OMG, as my kids would say. I think we are related, albeit distantly. See below.....
My dad had an uncle (?) named Johnny Huha (could be the "Moo-ha" you remember). I also think the name Helen Jackson is familiar. What I'll do is get my dad to log onto this forum and see if he recognises any of the names. But definitely, Johnny Huha is familiar. He was from (I think) my grandmother's side of the family (she married Ambrose Campion) - she was of Slovakian descent.
