Joseph Rubinstein family at find-a-grave:
Joseph Rubenstein entered the Russian artillery in 1893 There he learned the carpentry trade, which had been practiced by his father and at least one brother and he picked up the habit of excessive drinking that was to plague him for the rest of his life. While in the army, he married Fannie Turek Rutkowski; the marriage was arranged, as was customary, by a professional matchmaker. According to his oldest son, Joseph Rubenstein served in China, Korea, and Siberia, detesting these places and army life. Eventually, in 1898, he simply "walked away" from it and about 4 years later he went to England and Canada, entering the United States in 1903. Settling in Chicago Joseph Rubenstein joined the carpenters union in 1904 and remained a member until his death in 1958.
Fannie Rubenstein followed her husband to the United States in 1904 or 1905, accompanied by her children Hyman and Ann. An illiterate woman, she went to night school in about 1920 to learn how to sign her name. Although she apparently learned some English, her speech was predominantly Yiddish, the primary language of the Rubenstein household. Still, Mrs. Rubenstein felt strongly that her children required an education in order to better themselves. She frequently argued about this with her husband, who had received little, if any, formal education and firmly believed that grammar school training was sufficient for his children.
The Rubenstein home was marked by constant strife and the parents were reported to have occasionally struck each other. Between 1915 and 1921, Joseph Rubenstein was frequently arrested because of disorderly conduct and assault and battery charges, some filed by his wife. In the spring of 1921, Jack Ruby's parents separated. The predominant causes of the separation were apparently Joseph Rubenstein's excessive drinking and Fannie Rubenstein's uncontrollable temper. She resented her numerous pregnancies, believed her husband to be unfaithful, and nagged him because he failed to make enough money.
At different times, the children were removed and became wards of the Jewish Home Finding Society or placed in foster homes. Fannie suffered from mental illness and spent time in and out of mental hospitals herself. She was admitted to Michael Reese Hospital on April 4, 1944, as a result of a heart ailment. Her condition was complicated by an attack of pneumonia and she died at the hospital on April 11, 1944. Her son Hyman testified that, perhaps because she favored the education of her children and they recognized her difficulties in rearing them during a turbulent marriage, they all remembered Mrs. Rubenstein with warmth and affection. The evidence also indicates that Jack, notwithstanding his earlier attitudes, became especially fond of his mother. Following his wife's death, Joseph Rubenstein stayed with the children in Chicago, where he died at the age of 87.
Children: Hyman & Ann (both born overseas), Marion, Eva, Jacob (Jack Ruby),Sam, Earl, and Eileen (all born in Chicago). One or two other children died in infancy.
