I have come across two instances now of a son having the same given name as the father. In both cases I do not know when the father passed. One is from present day Belarus from the late 19th century, the other is from present day Poland from the early 19th century. I’m assuming that the father passed away before the child was born, but has anyone else ever heard of another possible reason?
BUZILA and KILYAN from present day Moldova
GRUBER and FEINGOLD from present day Ukraine
SEIDLER/ZEIDLER, GROSSBARD, BERLIN, WICZYNSKY, PTAKEWICZ, GOODMAN, DOBROSZKA and BROWN/BRAUN from present day Poland.
PORTNOY, GERSHON and OFSAIOF/OVSAIOVICH from present day Lithuania
MNUSHKIN and KOLVARACHIK from present day Belarus
EISENSTEIN and ZALIO from present day Romania
