General Porter House

Ladd's father-in-law, Congressman Nathaniel Appleton Haven (1762-1831), bought it in 1809 and four years later Ladd bought it from him. By 1818, the Ladds had moved to the Moffat-Ladd Mansion and rented out this house. In the early 1820s, it was rented to Captain John Porter and his wife Eliza Chauncy Clark, and it was here that their son, General Fitz-John Porter (1822-1901), was born and lived until 1825. Today, General Porter's statue stands opposite the house and it is for him for whom the house is named. 

In 1833, Charlotte Haven Ladd, daughter of Alexander Ladd, married Samuel E. Coues (1797-1867) and they made their home in the house that has been her childhood home. Cous was a wealthy shipbuilder and merchant, but he is perhaps best remembered for his numerous humanitarian, charitable and intellectual endeavors. They lived here until moving to Washington D.C. in 1854, when they sold to Albert R. Hatch (1817-1882), "one of the most popular men in the city" whose family lived here until 1925.

Among those members of the Hatch family to live here was Rear Admiral James K. Cogswell. In 1925, the family sold the house to Admiral Douglas Eugene Dismukes (1869-1949) who'd won the Navy Distinguished Service Medal in 1918. During the Depression of the 1930s, he converted the mansion into two family homes. After changing hands several more times and after the addition of five dormers on the front of the house in 1981, it was given a much needed restoration in 1983 and converted into condominiums.
