322 Marlborough was designed by architect Willard Thomas Sears (of the firm of Cummings and Sears) and built for him ca. 1872. At about the same time, he also designed four contiguous houses on adjoining lots on Gloucester (9-11-13-15 Gloucester) to the west.
Willard and Marianne (Mott) Sears made 15 Gloucester their home. Willard Sears sold 9–11–13 Gloucester to his first cousin, Joshua Montgomery Sears, as rental property, and 322 Marlborough to his brother-in-law and sister, Charles W. Seabury and Elizabeth Willard (Sears) Seabury. Charles Seabury is shown as the owner of 322 Marlborough on the 1874 Hopkins map and on the 1883, 1888, and 1898 Bromley maps.
Charles Seabury was treasurer of the Calumet and Hecla copper mining companies.
At first, it appears that 322 Marlborough was the home of the Seaburys’ son, Frank Seabury. He is listed there in the 1875 City Directory, and Charles Seabury is shown as residing in Millbury.
By the time of the 1880 US Census, Frank Seabury’s younger brother, William, had joined him at 322 Marlborough. They were both broker’s clerks and later would be in partnership as stockbrokers. Charles and Elizabeth Seabury continued to live in Millbury. Their daughter, Elizabeth Sears Seabury, lived with them.
By the 1881-1882 winter season, Mr. and Mrs. Seabury and Elizabeth Seabury were also living at 322 Marlborough.
Frank Seabury continued at 322 Marlborough with his parents until his marriage in September of 1897 to Alice Barnard, after which they moved to the Hotel Agassiz at 191 Commonwealth.
Charles Seabury died in August of 1901. Elizabeth Seabury continued to live at 322 Marlborough with their son, William, and daughter, Elizabeth. The Heirs of Charles Seabury are shown as the owners of 322 Marlborough on the 1908 Broley map.
During the 1911-1912 winter season, Frank and Alice Seabury joined his mother and siblings at 322 Marlborough.
Elizabeth Seabury died in February of 1912. William Seabury and Elizabeth Seabury moved to Brookline; Frank and Alice Seabury moved to 845 Boylston.
In mid-1912, 322 Marlborough was purchased from the Seabury family by Dr. Franklin Warren White, a physician, and his wife, Ethel Plummer (Bowen) White. The transaction was reported in the Boston Globe on July 3, 1912. In 1911, they had lived at The Marlborough at 416 Marlborough, where he also maintained his medical office. They also maintained a home in Marblehead Neck.
Franklin White is shown as the owner of 322 Marlborough on the 1912 Bromley map, and Ethel B. White is shown as the owner on the 1917, 1928, and 1938 maps.
In early 1950, 322 Marlborough was acquired from the Whites by Charles A. Turner. By 1952, it had been converted into a three family residence. In April of that year, Charles Turner, applied for (and subsequently received) permission to increase the number of apartments from three to four.
By 1959, 322 Marlborough was owned by Michael J. Smith, a real estate agent. He and his wife, Georgia, lived in one of the apartments. They previously had lived at 69 Gainsborough. In June of 1959, he filed for permission to add a real estate office to the building. His application was subsequently abandoned.
The property changed hands, remaining four apartments.
In September of 1993, 322 Marlborough was purchased by John Edward McGinty, an investment banker, and his wife, Sarah Myers McGinty, a university admissions officer, educational planner, and author. In April of 2000, they applied for (and subsequently received) permission to convert it from four apartments into two apartments.
In August of 2006, the McGintys entered into a “Preservation Restriction Agreement” with the National Architectural Trust for the purpose of ensuring the preservation of 322 Marlborough’s exterior.
322 Marlborough remained a two-family dwelling in 2014.
