"Longwood" was the estate of Thomas Moore and his wife, Mary Brooke Moore.1 Mary's father, Roger Brooke IV, owned several thousand acres throughout Montgomery County during his lifetime. In 1794, four years after Roger Brooke IV's death and three years after Thomas and Mary's wedding, Mary inherited a 280 acre tract of land that was part of "Addition to Brooke Grove," one of her father's many properties.2 Thomas constructed a modest log cabin for his family on the land they inherited, which he named "Retreat." By 1817, Moore had become quite successful as a civil engineer and as the owner of a tannery on the western edge of Brookeville. He used his wealth to build a mansion around Retreat's original structure. His nephew Thomas McCormick, a trained house carpenter and future-Methodist minister, provided much of the labor for the house.3 McCormick re-named the house  "Longwood," potentially a reference to Napoleon Bonaparte's home on the island of St. Helena or to a nearby black mahogany tree which was said to have been imported from the same island.4 Moore lived at Longwood until his death in 1822.5 In 1830, Moore's widow sold the house to its builder, Thomas McCormick.6 McCormick owned Longwood until 1844 when he sold it to Sophia R. Hammond.7
