Groucho, unfortunately, was married three times; First to Ruth Johnson, their marriage lasting from 1920-1942, out of this marriage came his son Arthur and daughter Miriam. Next, he married Kay Marvis, their marriage lasting from 1945-1951, this marriage giving him his third and last child, Melinda. His final wife was Eden Hartford. Their marriage lasted from 1954-1969. His final girl was Erin Fleming. From what I've read of her she was a heartless woman. She hit him and because he was already 79 when he and Eden divorced, he was already not doing so well. He was having strokes at this time, making it worse, and reportedly, she would hit him, shove him, and trash talk him. On her birthday, Groucho had a minor stroke and he was lying in bed when she burst in his room and yelled at him "You had a stroke on purpose!" and continuing to yell about how he just did this to take the attention away from her. How do you have a stroke on purpose? Erin's influence on Groucho was controversial. Many close to him admitted that she did much to revive his popularity; these efforts included a series of one-man shows, culminating in a sold-out performance atCarnegie Hall, and an honoraryAcademy Awardthat was presented to him during his lifetime. Others, including Groucho's son,Arthur, described her inSvengali-esque terms, accusing her of exploiting an increasinglysenileGroucho in pursuit of her own stardom.

In the years leading up to Marx's death in 1977, his heirs filed several lawsuits against her. One allegation leveled against Erin was that she was determined to sell Groucho's favorite car, a Cadillac, against his wishes. When Arhur protested, it was said, Erin threatened, "I will slap you from here to Pittsburgh." Many people close to Groucho believed Erin was abusivetowards him. Arthur wanted temporary conservatorship of his father, and took Erin to court. According to the book Raised Eyebrows by Groucho's secretary Steve Stoliar, Erin had several personal problems; he stated in his book that she used drugs, and hadmood swings.
