I can only find birth data for Siegfried not Alfred. Siegfried with daughter Dr. Caroline Landau and wife Frieda Landau are mentioned in [[6000 's death announcement. [[60 speaks of "Friedl" as her brother. This would fit both Alfred and Siegfried. Caroline's death registry mentions Alfred Landau not Siegfried as her father. There are newspaper articles that Siegfried fled the Vienna due to some troubles with the law and kidnapped the wife of Julius Ellenbogen. It is possible that Kurt / Kirk is the result of an affair of Jenny while she was married and before Siegfried / Alfred was married to Frieda.
