Here is Alfred's obituary, published 25 Jan., 1919 in The Boston Daily Globe, pg. 10. This is the only write up I have found so far. I looked in the NY Times, but there was nothing.
HARRIMAN--In Jamaica Plain, Jan 24, Alfred C. Harriman, in his 32nd year, husband of May E and only son of Capt. and Mrs. Joseph Harriman. Funeral services at his parents residence, 811 Center St., Jamaica Plain, Sunday Jan. 28?, at 2:30 pm.
Alfred C. Harriman married Mary "May" Elizabeth Wright (Joseph, Marie "Mary" Boudreau) on Tuesday 11 Aug 1914 in Wiscasset, Maine. [Source: Maine State Archives]
Just a note; I found a May Harriman, widow, 32 yrs old, in the 1920 Manhattan census on West 135th St.(there was only one May Harriman in all of NY), it documents her as doing clerical work in studio. Living with her as roomers are Russell Mack and his wife.
Our May as born 31 May 1887 in Boston : ) She died, Apr. 1967 in Manhattan, NY, NY. Verified per her SSDI listing. I believe the May in the 1920 census is our May Harriman, nee Wright.

Joseph Harriman and Clara E. unknown were Alfred's parents, and both were supposedly born in Maine. Joseph Harriman was a policeman in J.P., hence the usage of the abbrev. Capt. in Alfred's obit. Info on Alfred's parents and birth come from the MA State Archives. [Harriman Alfred Clark Boston 1887 378 237 Birth]
