Wow! It took me a little while to figure this one out.But it actually is plausible for my g-grandmother's brother Josef Gence.
As I understand it, young Josephine Genz married Tripo in IL in about 1926.Then her family, some of whom were already here, assembled in Chicago.My family was Slovak, which would be included as Czechoslovakia at that time.The Slovaks, who long wanted their own country, did not get it until 1992. If this actually represents what happened, the sequence would be: Joe and Zusanna Gence in Philadelphia (1900), returning to Slovakland (1900), birth of children (1900-1908), death of Zusanna (after 1908), marriage of Josef to elder Josephine, death of Josef, emigration of children and Josephine to New World. There are a number of points to check against what I already know as true.But at least it has the virtue of being plausible, even if these guys don't turn out to be who I hope they are.
My g-uncle Joseph Gence was born in 1869.Elder Josephine would have been born in 1876.The age differential for the Slovak culture of the day would not have been very unusual.Young Josef (assuming he was born to first wife Zusanna) would have been born when his mother was 33 and his father 39.
