Hello, my husband's grandmother was Lena Laura "Helen" Eichstaedt (b. 3 Sep 1913 in Wisconsin, d. 24 Mar 1954 in Milwaukee, Milwaukee, Wisconsin) who married Lester Herman Fischer. Helen's parents were Richard Eichstaedt and Amanda Keller.
The earliest Eichstaedt I have is Johann Gottfried Eichstaedt (b. 10 May 1817 in Germany, d. 3 May 1894) who married Wilhelmina Berg.
I have much information on the family, including many pictures.
Please, if anyone has a connection to this family or information, feel free to contact me.
