George D. Rockwell (1831-1899) of White Plains and Mt. Vernon, N.Y. (R201 in the 1st edition, R204 in the 2nd):

I gave his wife Semantha's father as Gilbert Tompkins Odell. Ernest Crewdson found this as a marginal note written in a copy of F.F. Spies' compilation of gravestone inscriptions at White Plains Rural Cemetery, but he doubts its accuracy. All records he has seen only give a middle initial T. He suspects that it stands for Taylor, given that one Gilbert Taylor, in a will dated 13 Oct. 1803 [Westchester Wills, book F, p. 11-13] mentions Moses Odell and his sister Anna. Moses, who was perhaps adopted by Taylor, was the father of Moses T. Odell.
