Marian A. Sargent
Mrs. Lucius Manlius Sargent
By the 1882-1883 winter season, 184 Beacon was the home of T. Jefferson and Hetty Coolidge’s son-in-law and daughter, attorney Lucius Manlius Sargent and Marian Appleton (Coolidge) Sargent. They previously had lived at 231 Beacon.
In May of 1883, Lucius Sargent applied for (and subsequently received) permission to build a stable at the rear of the property.
Lucius Sargent died in November of 1893, and Marian Sargent moved thereafter to the Tudor at the corner of Beacon and Joy Streets. By the 1903-1904 winter season she was living with her widowed father at 315 Dartmouth (Hetty Coolidge had died in March of 1901).
