The work of Seton and Beard is in large part the basis of the Traditional Scouting movement. Seton served as Chief Scout of the BSA from 1910 to 1915 and incorporated what he believed to be American Indian elements into the traditions of the BSA. He had significant personality and philosophical clashes with Beard and James E. West. In addition to disputes about the content of Seton's contributions to the Boy Scout Handbook, conflicts also arose about the suffragist activities of his wife, Grace Gallatin Seton Thompson, and his British citizenship. The citizenship issue arose partly because of his high position within the BSA and the federal charter West was attempting to obtain for the BSA requiring its board members to be United States citizens. Seton drafted his written resignation on January 29, 1915, but did not send it to the BSA until May. The position of Chief Scout was eliminated and the position "Chief Scout Executive" was taken on by James West. In 1931, Seton became a United States citizen. Personal life British by birth Seton was not naturalized as Canadian (as status did not legally exist until 1947; he thus remained a British subject) and became an American in 1931. He was married twice. His first marriage was to Grace Gallatin in 1896. Their only daughter, Ann (1904–1990), later known as Anya Seton, became a best-selling author of historical and biographical novels. According to Ann's introduction to the novel Green Darkness, Grace was a practicing Theosophist. Ernest and Grace divorced in 1935, and Ernest soon married Julia Moss Buttree. Julia wrote works by herself and with Ernest. They did not have any biological children, but in the 1930s they sought to adopt Moss Buttree's niece, Leila Moss, who lived with them for years in New Mexico. In 1938, they adopted an infant daughter, Beulah (Dee) Seton (later Dee Seton Barber). Dee Seton Barber, a talented embroiderer of articles for synagogues such as Torah mantles, died in 2006. Seton called his father, Joseph Logan Thompson, "the most selfish man I ever knew, or heard of, in history or in fiction." He cut off ties completely after being made to pay off an itemized list of all expenses he had cost his father, up to and including the doctor's fee for his delivery, a total of $537.50. Seton's parents lived out their lives in Toronto, as did brother John Enoch
