70 Commonwealth was designed by architect Nathaniel J. Bradlee and built ca. 1869, one of two contiguous homes (70-72 Commonwealth). It appears likely that 70 Commonwealth was built by Standish and Woodbury, masons, and N. O. Hart, carpenter, who were credited as building 72 Commonwealth in a January 1, 1870, article in the Boston Daily Transcript Supplement.
70 Commonwealth was built as the home of Catherine Dorcas Brewer and Elizabeth Haskins Brewer, who were sisters; 72 Commonwealth was built as the home of their brother and sister-in-law, John Reed Brewer and Caroline Francoeur (Sayles) Brewer.
The land for both houses was purchased from the Commonwealth of Massachusetts on July 28, 1868, by John Brewer. He then sold his sisters the lot for 70 Commonwealth, with a 22 foot frontage, on August 4, 1868, and retained the lot for 72 Commonwealth, with a 30 foot frontage.

By the 1881-1882 winter season, 70 Commonwealth had become the home of John and Caroline Brewer’s son-in-law and daughter, General Wilmon Whilldin Blackmar and Helen Renouf (Brewer) Blackmar. They previously had lived at the Hotel Brunswick (southeast corner of Clarendon and Boylston). They also maintained a residence in Hingham on the property of World’s End Farm, owned by Helen Blackmar’s parents.
Wilmon Blackmar had been a Captain in the US Army during the Civil War, receiving the Medal for Honor for distinguished service at the battle of Five Forks on April 1, 1865. After the war, he became a lawyer in Boston, and served as Judge Advocate General of Massachusetts, with the rank of Brigadier General, from 1873 to 1883. He was a leader of the Grand Army of the Republic and was elected its Commander-in-Chief in 1904.
