Please note I have updated the parents to Wolf and Johanna Edel (nee Herpe) based on a reference in Joachim Zdrenka's book that Louis is their child. This means that Zaddek is his uncle. Please note that Hedchen married Zaddek in 1912, so even if Zaddek was the father, it would be likely that Eva is the mother. For reference, Louis' birth record is #43 in the 1901 StA Krojanke register.
