  RESEARCH_NOTES: 1. Email dated 8 Dec 2011 from Lucille Maitino, granddau. of Rudolf Herzenberg : "My Grandfather Rudolf siblings, Herman married Paula?, had two children Taube & Gerald. Brother Leo went off to war, Bertha stayed in Latvia, Clara married Serjay Ismailoff, then Louis Larsen, and then Irwin Orton. I am not sure of dates, but she lived in many countries, the longest Shanghai, then NYC, New York, as that is where Irwin died late 1960's. Clara died in 1979."
