I believe that Sarah Irvine,d/o David & Jane Kyle Irvine,of Madison Co,KY, may be the Sarah named as wife of Joseph Batterton. This Sarah would have been sister-in-law of the Betsey Hockaday who married Sarah's brother William Irvine. Need to know data on this Sarah Irvine. Did she die early? Did she marry someone else? She could be the Sarah called sister of Betsey Hockaday. If so, this would open up a new line.
