Margolies had four children — two sons, Hyman and Samuel, and two daughters, Ida Newman and Etta Schlang. Etta, or Hadas in Hebrew, married Isadore Schlang and was the mother of the future
Rebbetzin Gerdie Lookstein. She died in 1932. Samuel Margolies, or Shlomo Zalman in Hebrew (1877-1917), followed his father into the rabbinate. He was the rabbi of Congregation Anshe Emeth in Cleveland, Ohio from 1904 to 1917, when he died in a car accident. During his time there, he founded, led, and promoted many Orthodox institutions, including the Union of Jewish Organizations, the Cleveland Kehillah, the Hebrew Institute, a kosher kitchen at
Mount Sinai Hospital, the
Yiddishe Velt newspaper, and Talmud Torah schools. He and his wife Rena Franks Margolies had two sons, Asher and Daniel. Architectural and art critic
John Margolies was Asher's son.
Legacy Margolies died at age 85 on August 25, 1936 at the Carlton Hotel in
Belmar, New Jersey, with his wife and remaining two children at his bedside. Margolies had been the oldest living rabbi in America. Lookstein founded the
Ramaz School in 1937, which was named in honor of Margolies, known by the acronym of "
Rabbi
Moshe
Zevulun." Lookstein's son
Haskel Lookstein, was a member of the school's inaugural class of six students. The Ramaz School had an enrollment of approximately 750 students in 1990, which had grown to 1,100 students in elementary through high school by 2007. ==References==
