Her real name is Anna Margaretha Caroline Gertrud Zimmer. Lena is a nick name for Caroline. I was looking for another child but there's only one. She came over fromGermany with Johannes Kochler and they married 1866 shortley after arriving in Dwight, Livingston, Illinois. If anyone is looking for her tombstone it says Lena Kochler. She is in the Oaklawn Cemetery. She was the half-sister to Philippe Konrad Zimmer, his father was Philippe Konrad Wuest.
