My research findings from church records, land records, tax records, etc. strongly suggest that Jacob Grove(s) of Rowan/Wilkes/Ashe Counties, NC, during the late 1700s, was from the Graff family of Cocalico Township, Lancaster County, Pennsylvania. Three generations of this family were among the earliest members of the Ephrata Seventh-Day Brethren community in Cocalico, including Jacob's parents, grandparents, and his siblings. Jacob was Brethren while living in Wilkes/Ashe, North Carolina. Jacob left Cocalico Township in the 1760s. I figure he moved slowly south to North Carolina. His children's given names--Jacob, Joseph, Daniel, Elizabeth, Christina, Susanna, Catharine, Peter, etc.--were common among the related Graff families of Cocalico. Jacob Groves' children and their families moved from Ashe County, NC, to Muhlenberg County, KY, about 1801 and shortly thereafter. The daughters married Henry Shutt and three Gates men: John, George, and Michael. These Groves-Shutt-Gates families were Brethren, moving to Sangamon County, Illinois, about 1830, where they organized the Sugar Creek Brethren Congregation. The elder-in-charge was Isham Gibson who married Elizabeth Gates, daughter of Michael and Catharine [Groves] Gates. Dwayne Wrightsman gggg-grandson of Jacob Grove via his daughter Catharine who married Michael Götz/Gates.
