I am descended from the Younce/Yonce family who married into the Rollen/Rolland/Rowland family. Samuel Andrew Younce married Peggy Susannah Rolland d/o Joseph and Elizabeth Fouts. Their son William married Sarah Barnes d/o Elihu Barnes and Mary Rolland. Mary d/o Joseph and Elizabeth Fouts. What information do you have on these Yonce families. How do they connect up with Daniel Boone???
