Woman's Journal sites in Boston
The Woman's Journal was founded in 1870 by Lucy Stone. It was published in Boston as a weekly newspaper until 1917, when it was absorbed into The Woman Citizen of New York City. It was the preeminent woman suffrage journal.
The journal was edited by Mary A. Livermore for a few years, then by Lucy Stone and her husband Henry B. Blackwell. Later, their daughter Alice Stone Blackwell was the editor. She even continued with The Woman Citizen.
The journal had a number of locations in Boston. Most were within the block across Beacon Street from the Massachusetts State House. See map here. The locations are listed below, based on my research, which included a sampling of the journal's issues. (Updated 4/20/20 & 7/4/20, thanks to information from Joelle Million via Fredie Kay.)
1870-1876. 3 Tremont Place
1877-1879. 4 Park Street
1879-1887. 5 Park Street
1887-1908. 3 Park Street (21 years at this address)
1908-1910. 6 Beacon Street (same block as all of above)
1910-1916. 585 Boylston Street ("beehive" of suffrage organizations)
1916-1917. 45 Boutwell Street in Dorchester (Alice Stone Blackwell's house, inherited from Lucy Stone, built in 1872, used as center for suffrage activities, destroyed by fire in 1966)
In the 1881/82 Boston Directory, Henry Blackwell and Lucy Stone, married to each other, and the treasurer and editor, respectively, of the Woman's Journal at 5 Park Street, were listed (separately) with a home on Boutwell Street at the corner of Train (pages 115, 957).
The locations of the journal and other woman suffrage organizations, after 1900, are shown in the chart at the bottom of the page here.
