All of The Three Stooges were married, some even multiple times:
Sometime in his late teens, Curly Howard found another love and married a young girl whose name remains a mystery to this day. His mother, Jennie Horwitz, the matriarch of the family, was against the idea of Curly's marrying at such a young age and, before six months had gone by, had the marriage annulled.
Curly married three times after his first marriage was annulled. On June 7, 1937, he married Elaine Ackerman, then Marion Buxbaum then Dolly Sallin.
Moe Howard married Helen Schonberger, a cousin of magician Harry Houdini.
Larry Fine married Mabel Haney in 1927. The marriage resulted in two children, his daughter Phyllis Fine, his son Warren Wolf, Sports Anchor for CBS 2 News in New York.
Lastly, Shemp married Gertrude Frank (28) a fellow New Yorker. They had only one child, a son.
