Hi - I don't know of any Julius in the family. Where did your family emigrate from?
I do know a little more about my great grandfather's twin Wilhelm.His father was also Wilhelm. He and his children were all from the Vistula river area (Kempa Karolinska or Kempa Glowinski).His wife was Eleonora Krentz. They were married in 1876. Some of the children emigrated, some didn't.They were: Otilia, Eduard, Hulda, Wilhelm, Augusta, Bertha, Emma, Pauline, Amanda and Guido.
