My great-grandfather was a Scheffler... his name was Rudolph. We don't know where the family lived before they emigrated. He emigrated as a child around age 2 from Hamburg, Germany in about 1892 or thereabouts. It is my understanding that his mother's name was Anna, and that she died maybe in Germany, before they emigrated.Not sure of father's name, but was possibly also Rudolph. Family rumor says he had a twin brother that got lost in New York City, and was never found.
He also had an older sister, Anna, who emigrated I think at the same time. I know he had other siblings, but don't know their names or any other info.
I'm also looking for more info about the family... he appears to be listed with some of the Jewish genealogical societies according to the info here.
