In page Groucho Marx:

"

The Marx family was Jewish.[5] Mother Miene "Minnie" Schoenberg, and her family came from Dornum in northern Germany when she was 16 years old. Father Simon "Sam" Marx, changed his name from Marrix, was called "Frenchie" by his sons throughout his life, because he and his family came from Alsace in France.[6] Minnie's brother was Al Schoenberg, who shortened his name to Al Shean when he went into show business as half of Gallagher and Shean, a noted vaudeville act of the early 20th century. According to Marx, when Shean visited, he would throw the local waifs a few coins so that when he knocked at the door he would be surrounded by adoring fans. Marx and his brothers respected his opinions and asked him on several occasions to write some material for them.[citation needed]
