Marguerite, the oldest Marsh child, also became an actress. Mae also had an older brother named Oliver, and younger sisters, Frances and Mildred.
May Marsh remarried a man named William Hall and moved with her new husband and children to California. By this time, older sister Marguerite (born Margaret) was married to Donald Loveridge and had a daughter named Leslie.
In fact, it was actually the queen of silent film herself, Ms. Pickford, that inadvertently gave Mae her big break in film. Mary was getting sick and tired of playing scrappy little girl roles and put her foot down when another film of the same ilk came her way. In response, D.W. Griffith blackmailed her by saying she wouldn't get a bigger role in another picture if she turned the other one down. This just pissed Mary off even more, as well as the other actresses in the studio. Well, everyone that is but Mae, who just wanted any part! She got the role and I am betting both she and Mary recovered.
In 1915, she had lead roles in Griffith's epics The Birth of a Nation and Intolerance a year later.
Unlike many of her fellow silent stars, Mae made a smooth transition into talkies. She appeared in such notable films as Rebecca of Sunnybrook Farm (1932) with Marian Nixon, The Grapes of Wrath (1940) with Henry Fonda, and How Green Was My Valley (1941) with Walter Pidgeon.
Her last screen appearance was in 1964.
She was buried at Pacific Crest Cemetery in Redondo Beach, California.
Mae was only married once, to publicity agent Louis Lee Arms. They were married from 1918 until her death. They had two daughters, Mary and Marguerite, and a son, Brewster. Louis Arms actually lived to be 101!
So, around 1918, Ernest Hemingway told family and friends that he at one time was engaged to Mae but she had decided against marrying him. Years later Mae was asked about this story and said that she never met Hemingway but would have like to! Interesting...
