She did much by the circulation of petitions to secure the passage in New York in 1848 of a law giving a married woman property rights; and in the same year on the 19th and 20th of June in Seneca Falls, whither the Stantons had removed in 1847 from Boston, was held, chiefly under the leadership of Mrs Mott and Mrs Stanton, the first Woman's Rights Convention.
Her husband, who was prominent among the founders of Swarthmore College (1864), died in Brooklyn, New York, on the 26th of January 1868; and Mrs Mott died on the 11th of November 1880 near Philadelphia.
Recent grail researches have made it most probable that that mysterious talisman was originally the vessel of the ritual feast held in honour of a deity of vegetation, - Adonis, or another; if the Round Table also, as Dr Mott suggests, derives from a similar source, we have a link between these two notable features of Arthurian tradition, and an additional piece of evidence in support of the view that behind the Arthur of romance there lie not only memories of an historic British chieftain, but distinct traces of a mythological and beneficent hero.
However this may be, and it seems probable that Dr Mott is right in his identification, the pseudo-chroniclers and romance writers certainly had in their minds a genuine table, although, probably, one of magical properties.
At thirteen she was sent to a Friends' boarding school, at Nine Partners, near Poughkeepsie, New York, where James Mott (1788-1868), who like her was of old Quaker stock and whom she married in 1811, was then a teacher.
About 1840 Mrs Mott also took up the cause of woman's rights.
Professor Martin long since suggested that a key to the problems of the Arthurian cycle was to be found in a nature myth: Professor Rhys regards Arthur as an agricultural hero; Dr Lewis Mott has pointed out the correspondence between the so-called Round Table sites and the ritual of nature worship; but it is only with the discovery of the existence of Bleheris as reputed authority for Arthurian tradition, and the consequent recognition that the Grail story connected with his name is the earliest form of the legend, that we have secured a solid basis for such theories.
