MORTON: The Morton and Barclay and Gentle Families, our Scottish Ancestors in Rock County, Wisconsin and Other States with their Scottish Ancestry (Softcover)by Margaret Harris Stover. 1989. The Horton family lineage traces back to Scotland, specifically the parishes of Cupar and Honinail in Fife, where the earliest records of John Horton and Jane Barclay's marriage date to February 20, 1792. Extensive research into Scottish parochial records has revealed significant details about the family's ancestry, including descendants like James Horton and his children, who were agricultural laborers in Abdie.
