I did a record in the ssdi for a Nicholas Zobec who was born in 1905, married to Katherine. The weird thing is that the living descendants are sure that Nicholas is Margaret's brother, but that doesn't make sense at all, considering the age difference and the age of the parents, Charles and Julia. Also, even though I found that ssdi record, I can't find Nicholas Zobec (or any variation of Zobec) on a census in 1910, 1920 or 1930. I think there must be some unusual circumstances surrounding the family relationships here... maybe he was adopted? Maybe he's really a cousin or an uncle? I'm not sure.
