I found a Preston Lawrence Shelton in some of my old handwritten records. According to this he was born ca 1820 and died Nov. 18, 1895 in Owen Co., KY. He married Ellen Kitchen. However, I have only one child listed for him--Daniel Samuel (b. July 16, 1856, Owen Co., KY; d. Sept. 30, 1903, Owen Co., KY) m. Nancy Ellen Judy on Mar. 10, 1880 in Owen Co., KY. Daniel had 2 children: Ben Wilmer Shelton (no further info) and Ira Matthias Shelton (b. Apr. 11, 1883, Owen Co., KY; d. Mar. 9, 1940, Louisville, KY) m. Effie Goddard (b. June 26, 1888, Owen Co., KY) on Feb. 10, 1910 in Great Crossings, Scott Co., KY.
Sorry, I don't have parents for Preston either.
