Though he had previously gone by "Taft," "T," and "Ezra," following his calling Benson began going by his full name. He explained that George Albert Smith, president of the Quorum of the Twelve, advised him: "Now, Brother Benson, in order that we not get you and your great-grandfather mixed up in Church records, we suggest in view of the fact that he always signed his name 'Ezra T.' that you spell yours out fully, 'Ezra Taft.'" Benson then states, "So I've made that a practice because of the counsel of George Albert Smith, who was my file leader as president of the Twelve." (3)

[Ezra Taft Benson diary] This is a day I shall never forget. Flora [Amussen Benson]7 and I met in the Celestial Room of the [Salt Lake] temple at 12:30 [p.m.] and in line with the recommendation of Pres[ident] [Heber J.] Grant received our second blessings under the hands of Elders Geo[rge] F. Richards and Jos[eph] Fielding Smith of the Council of Twelve. Our hearts swelled to overflowing with gratitude for the Lord's rich blessings. (1)
