I've read through your "Miller" postings and am fairly convinced that there we have the correct Jacob Miller and Sarah Wilkin.I have the Wilkin(s) line back to Johann Gottfried Wilkin (b. 1721, Weiler, Baden, Germany)"1727 Came to the USA with parents on the 'William & Sarah' Emigrated 1756 received a Lord Fairfax Land Grant in Shenandoah County - along with his brother, George." This quote came from the Johannes Hottel book which has a goodly bit of information on the Wilkins family as well. I've not tried to take the Wilkins back into Europe.
What cemetery in Licking Co. are your ances. (Jacob & Sarah Miller) buried? I have other ancestors who were from Licking Co., Have you run across any Shuler's?
