From the 1780s until 1870, almost all of Ashmont Hill (west of the present train station) was a farm, with the large farmhouse dating to about 1720, located at the corner of Washington and Welles streets, now the home to the Codman Square Branch of the Boston Public Library system. The farm was owned for a time by General Henry Knox. Sometime before 1850, the estate and mansion came into the possession of the Honorable John Welles, who died in 1855. The property would eventually be deeded to John Welles’ grandson, George Derby Welles, who was then just 26 years old and living in Paris with his wife, Armandine V. Derby. Welles wasted no time in developing the property through his agent, Boston Attorney Edward Ingersoll Browne. Streets were laid out and house lots were platted and sold, with some early properties built with much of the neighborhood developing by the turn of the century. The old Knox-Welles farmhouse would be razed by 1889, but the remainder of the neighborhood has since become a landmark neighborhood of Victorian-era homes. This mansard double-house at 67-69 Ocean Street dates to around 1872 and is one of the earliest properties in the area. Blending the Second Empire and Stick architectural styles, the handsome double house is said to have been designed by architect Luther Briggs for George D. Welles and rented to tenants.
