Quinn Park bears the name of Mary Berkemeier Quinn (1890--1967), an attorney and Republican Party Committeewoman who served as Cook County Public Guardian from 1942 to 1949. Quinn was a director of the Women's and Children's Hospital, and president of the State Federation of Women's Clubs and the National Republican Women's Club of Chicago. Quinn and her husband, Edward M. Quinn, lived on a wooded lot in Forest Glen's picturesque Edgebrook neighborhood, which had been developed in the 1890s as a suburban retreat for railroad executives. When Edward Quinn died in 1980, he left their property to the Chicago Park District. Under the terms of the bequest, the park district officially named its new park the Mary Berkemeier Quinn Park of Trees. As the name implies, the property is composed of a grove of black oaks, white oaks, maples, lindens, cottonwoods, and elms - all trees native to Illinois. In 1988, the wooded park became part of the City of Chicago's Old Edgebrook Historic Landmark District.
