My great-great grandfather Marcus Silberstein and g-g grandmother Deborah were from Iasi, possibly around 1820. The name was changed in the next generation to Arginteanu, so my grandmother and her seven brothers and sisters had that name when they came to the U.S., along with here parents Solomon and Zelda. Other relatives were Jacobs, Samuel (g grandmother's maiden name), Percian (g grandmother's mother's maiden name), from Bucuresti. There must have been other Silberstein's in Iasi. A grand-aunt told me the chief rabbi in Iasi was an ancestor. If this corresponds to anyone's information, please let me know. And if you've had research done in Iasi, I'd be interested in that too. Thanks.
