Ggggfather's brother Wilhelm Ernst Frederick Spiegelberg and wife Louise Caroline Dorothea Kohrt arrived in US May 1866 and traveled with daughters Henrietta W A Pribbernow, Augusta and Albertine Spiegelberg. I'm trying to locate marriage and family information on sister Albertine. They settled in Waupaca CO, WI. I have Augusta m. Langner; a sister E.W.L. m. Mader, and son F.F. m. a Much. There is a 6th child b. about 1836-1840 that I would like to identify. May have been female Spiegelberg married before coming to US in 1866 as Henrietta Spiegelberg Pribbernow did and traveled under the married name. Need to know the married name.
