Wiggin met dry goods (specifically, linen) importer George Christopher Riggs on her way to England in 1894. The pair are said to have hit it off and had agreed to marry even before the ship docked in England. In the Ellis Island logs from Wiggin's 1894 trip back to New York City from Liverpool, the two sign their names next to each other, indicating their closeness. The pair married in New York City on March 30, 1895 at All Souls Church. George Riggs soon became one of Wiggin's biggest advocates as she became more successful.
