Mrs. Trump was born Mary MacLeod on the Isle of Lewis in Scotland on May 10, 1912. On a visit to New York City in the 1930's, she met Fred C. Trump. They married in 1936 and settled in Jamaica Estates, and Mr. Trump went on to become one of the city's biggest developers. Mrs. Trump was the mainstay of the Women's Auxiliary of Jamaica Hospital and of the Jamaica Day Nursery. The Trumps were also active in the Salvation Army, the Boy Scouts of America and the Lighthouse for the Blind, among others. A pavilion at Jamaica Hospital Medical Center bears their name. They also gave buildings to the National Kidney Foundation of New York/ New Jersey and to Community Mainstreaming Associates of Great Neck, N.Y., which provides homes for the disabled.
