I'm asking on behalf of a cousin.
This is what I know about them:
Ernst, born in Germany in 1896, died in New Jersey in 1976.
Else, born in Germany in 1902, died in New Jersey in 1993.
Erich, born in Germany in 1929, died in 2011.
Any leads to descendants of the Liebreichs, or relatives of Else from the Bergmann side, would be greatly appreciated.
