The first known resident of the area was General McDonald who fought for the Continental army during the Revolutionary War. The name Guilford was supposedly named after the Battle of Guilford Court House in North Carolina, in which McDonald was wounded. His son William McDonald inherited his estate in 1850 and built the Guilford Mansion. In 1872 the property was purchased by Baltimore Sun founder, Arunah S. Abell, and would remain in his family for 35 years. In 1907 the property was purchased by the Guilford Park Company who wanted to develop the area into a sophisticated suburban neighborhood on the edge of expanding Baltimore. In 1911 they consolidated with the Roland Park Company and together purchased 210 acres in North Baltimore. Frederick Law Olmsted, Jr. was hired to do the landscape and street design. He is responsible for giving the neighborhood its distinct curving streets and terrain. The plan included three parks, “Little Park,” “Stratford Green, and “Sunken Park. In 1939 a fourth park was created called “Guilford Gateways.” The company spared no expense on utilities, streets, drains and other infrastructure to create a modern and an attractive living destination for the Baltimore elite. The houses were designed by some of the most prominent Baltimore architects of the era, included Edward L. Palmer, Bayard Turnball, John Russell Pope, W. D. Lamdin and Laurence Hall Fowler. The houses were primarily built in brick or stone and were designed in the popular revival styles of the early 20th century. In 1913 the new neighborhood opened to much local praise. After the completed sales of all the houses in Guilford, the Company allocated the Guildford Association to maintain the integrity of the neighborhood. The Association upholds the covenants of the Deed and Agreement left by the Roland Park Company.
