I believe I am a great grandson of Sigmund Lus. According to my research, he was married to Pauline Lus and had at least two children: Milton and Isabel Lus. Isabel Lus married three times, but the first time was to Alexander Mendelovits, and they had two children, Louis and Pauline. Pauline is my mother, and she is still alive and well and living in San Diego, California. Louis called himself Louis Lus and also lived in San Diego, California until his death in 1991. Please let me know your relationship to Sigmund Lus.
