Rainbow Hill is located on Park Heights Avenue in Owings Mills, Maryland. I was here that Henrietta Louise Cromwell, the step-daughter of Philadelphia lawyer, Edward T. Stotesbury, married Walter Brooks, a Baltimore contractor. She was given this Baltimore County mansion by her step father as a wedding gift. The home was completed in 1917. She later divorced Brooks and married General Douglas MacArthur in 1921, after the pair met at a party at West point. In 1925 he was assigned to a post in Baltimore and the couple moved here to the mansion, newly named Rainbow Hill in honor of his division in World War I. She often left him for long periods of time while she lived the life of a socialite, eventually leaving him here permanently when she moved to New York. They were eventually divorced in 1929. In 1930 she married actor Lionel Atwill here at the estate. He was a broadway star soon to find horror movie fame in Hollywood. The rocky marriage marriage ended in 1940 and Louise soon sold the estate. The Georgian-style mansion passed through several hands before the Baptist home acquired the mansion in 1963.
