Noble had real business ability, and before his untimely end was rapidly acquiring a fortune. He possessed a magnificent voice, and his singing made a sensation. Very old men in Middlebury who remembered it, later said that for purity of tone and beauty they had never heard a voice equal to it (Private letters of The Stewart family of Middlebury, Vermont. Selected and edited by John E. Stewart, 1968. Sheldon Museum, Middlebury, Vt.)
The property which he left rehabilitated the fortunes of the family which had suffered from various causes dating from the destruction of Captain Stewart's Inn at Ticonderoga. Noble moreover was a man of high principle and from his letters one can see that he always acted from high motives. He possessed a magnificent voice and his singing made a sensation. Very old men, whose memories went back to his time, told his nephew, Ex-Governor Stewart, that for purity and beauty they had never heard a voice that approached it. (Severance, B. Frank. Genealogy and biography of the descendants of Walter Stewart of Scotland and of John Stewart who came to America in 1718 and settled in Londonderry, N.H. Greenfield, Mass. : T. Morey & Son, 1905, pg. 81). Noble was probably named after Noble Hine, husband of Patience (Hubbell) Hine and father of Homer Hine. The Hine family were great friends of Capt. John Stewart's (Noble's father's) family (Severance, pg. 177).
