Margaret Julia Mitchell[2] (June 2, 1832 – March 22, 1918) was an American actress, born in New York City.

Her southern sympathies, charismatic personality and profession made her a warm, close friend of John Wilkes Booth, but also earned her the admiration of Abraham Lincoln, who invited her to tea in the Executive Mansion and enjoyed her performances at Ford's Theatre.

Hannah afterward married Maggie's father, Charles S. Mitchell (1805–1886), to whom Lomax's bookbinding business had been sold.

[10] Mitchell's 1st cousin, Joseph Dodson Greenhalgh (1821–1886), recalled stories that circulated in the English side of the family about the actress's salary, her servants, accouterments, and jewelry.

[12] Maggie's maternal half-sister, Mary Mitchell (née Lomax; 1833–1908) – also an actress – was married to John William Albaugh, Sr. (1837–1909), an actor and theater operator, notably, from 1884 to 1894, proprietor of Albaugh's Grand Opera House (2,000 seats) in Washington, D.C. After her death on March 22, 1918, in New York City, one of the wealthiest actresses in the world (primarily in Manhattan and Long Branch, New Jersey, real estate), Mitchell was interred in Green-Wood Cemetery in Brooklyn.
