"Was this likely? Was it at all common that a family would move that far away from one hometown to another?"
There are all sorts of reasons, but some of our ancestors moved long distances. My grandfather was supposed to have been born in Berdichev, my mother told me growing up, but his brother told the Baseball Hall of Fame, apparently, that he was born in Odessa 3 or 4 years later (I bet you never heard of Lefty).
