Benjamin Cox did not live at any time in the Jericho neighborhood. His life-long residence was near the White River Friends Meeting. However, he was prominent in the Jericho Friends Meeting through the fact that he often
preached there. He owned a quarter section of land within a mile of the Meeting-house. Further, his son William B. married Margaret Peacock (daughter of Abram Peacock) and lived on this land as well as exhorted at Jericho for a number of years. Despite the great number of Coxes in the early neighborhood, it seems that all who remain today are descended from this same Benjamin Cox, who never lived there. He is therefore worthy of inclusion in this book.
Benjamin Cox was born in North Carolina in 1785 and moved to Randolph County with his parents, John and Patience (Piggott) Cox, in 1817. He married Ann Rhoads in North Carolina. They had eight children, two of whom married Jericho folks. Benjamin Cox taught in the early schools of White River about 1820, was a recorded minister of the Friends, was one of the first three Commissioners of Randolph County, and helped to lay out the town of Winchester, as County Seat. He died in 1847 and is buried at the White River burying ground.
