I do not have the listing of the children of Jefferson Motsinger but did find Nancy Keaster on the internet. Her older brother Abraham was born in 1839 in KY and this agrees with the notes that Nancy was born in KY. Her older brother died at Crab Orchard, IL. Her father Lewis Keaster born 1803 at Crab Orchard. Died 1847. Her motherJane Richey born about 1814 at KY. Died Williamson, ILL.
Lewis Keaster's father is LewisKeaster and mother is listed only as Mary.
The birth date of Nancy Keaster at the internet site is 1835.In the newspaper article a Nancy Motsinger (1837-1910)is buried at Green Ridge Presbyterian Church cemetery eight miles from Russellville, KY.
