I’m trying to trace my grandfathers ancestors. i believe the name had been changed. why is BLUM such a common name? growing up in michigan there weren’t that many, but in NYC There are a million. i’ve not be able to find his naturalization papers, but his records show he was was Satanov/Sataniv. His grave is also in a section with that city designation. Any recommendation as to how i might find his original surname? thanks for any suggestions. -- Barbara Blum
