One afternoon in the Autumn of 1855, two young men were drinking coffee at Vinton’s, a Boston confectionary saloon. Both were bright and respectable, with promising futures. William Sumner, age 19, was a cousin of Massachusetts Senator Charles Sumner and had recently completed a course of mercantile studies, preparing to enter his brother’s ship chandlery business. His friend, Josiah Porter, was a Harvard graduate and a lieutenant in the City Guards.
A pair of attractive young ladies sat down at the table next to them. Nelly Dalton and Fanny Coburn were sisters, the daughters of John Gove, who owned a clothing store in Boston. Fanny recognized Mr. Porter and reminded him they had been introduced at a ball for the City Guards the previous February. The four struck up a conversation, and although both ladies were married, they became quite flirtatious. Before they left, they told the men that they often came to Vinton’s and hoped they would see them there again.
