I am looking for any information about my ancestors, the Mandelstams. Nachern/Nachem Mandelstam and Bertha came from Vilma or Ligun, Russia/Lithuantia on a boat called the Kaiser in 1891. They brought their son Leo and settled in New York City, specifically the Rockaway area in Queens. Leo Mandelstam married Lillian and they had children named Madeline and Julian. Julian and Gladys Mandelstam had my mother Marguerite (or Peggy), and I am interested to know if he had any other children later in life. I believe he moved to Nevada sometime after he served WW2.
