I have the book "The Kinnears and Their Kin," 1916 by Emma Siggins White.Though, like all genealogical works, it has errors, it is still a very good book.
According to this book, Rev. Gideon Draper Kinnear b. 13 Apr 1809 in Venango Co. PA, d. 8 Sep 1875 in Ohio, married June 1873 in Wilkinsburg, Allegheny Co., PA to Matilda GRAY b. in Allegheny Town, in PA in 1820, dau. of Rev. James Gray, a wealthy local preacher in the M.E. Church."Rev. Gideon Draper Kinnear was probably named for Bishop Gideon Draper, of the M. E. Church.He dropped dead in his pulpit in Ohio." He was the son of William KINNEAR and Mary Allender.
The following obituaries from "Spectator", Franklin, Venango Co.PA: 21 Feb 1855 "Died in this place, Monday, Feb 19, at res. of her son-in-law, N. R.
