Daniel Nelson Alley (1810-68) built this home about 1851. A founder of Jefferson, Alley was a prominent early landowner in Marion County. Several families owned the house before 1884, when Hector McKay (1835-93) bought the property. A veteran of the Civil War, McKay was one of the area's leading attorneys. His son, Arch McKay (1875-1954), retained ownership of the home until his death. Designed in the Greek revival style, it features a 4-room central hall plan. Recorded Texas Historic Landmark - 1986
