On September 14, 1886, in Richmond, she married Armstead Walker Jr. (1860–1914), a brick contractor. She spoke of her views on marriage: "And since marriage is an equal partnership, I believe that the woman and the man are equal in power and should by consultation and agreement, mutually decide as to the conduct of the home and the government of the children"They adopted a daughter, Polly Anderson, and had three sons: Russell Eccles Talmadge Walker born in 1890; Armstead Mitchell Walker born in 1893, but died seven months later; and Melvin DeWitt Walker who was born in 1897. The Walkers purchased a home in 1904 at 110 East Leigh Street, within the African-American
Jackson Ward neighborhood of Richmond. It was enlarged over the years to accommodate their children's families. In 1907 Walker fell on her front steps, damaging nerves and tendons in her knees. She suffered severe pain as a result and spent much of her last decade at home. In 1928 she used a caned wheelchair, adding a hand-operated elevator to her home, and modifying a 1929 eight-seat Packard to fit the chair. On June 20, 1915, Walker's son, Russell Walker, at age , shot and killed his father, Armstead. Russell had mistaken Armstead for a burglar, for whom both he and his father had been searching. Russell was arrested and charged with murder and, after five months awaiting trial, was declared not guilty. The loss left Walker to manage a large household. Her work and investments kept the family comfortably situated. Walker loved to entertain, and during this time, Walker still frequently invited black business, civic, and social leaders to dine at her house. Visitors included
W.E.B. Du Bois,
Langston Hughes, and
Mary McLeod Bethune. Russell never recovered from his father's death, and after eight years battling depression and alcoholism, died November 23, 1923. After Russell's death, his wife Harriet, or Hattie, and their daughter Maggie Laura Walker, moved in with Maggie Walker in Richmond. Hattie became a trusted advisor to Maggie within the Independent Order of St. Luke, quickly moving up the ranks. Walker died December 15, 1934. The cause of death on her death certificate was diabetes gangrene. Walker was inducted as an Honorary Member of the Nu Chapter of
Zeta Phi Beta sorority at the chapter's first meeting in 1926. == Legacy ==
