Mitchell Cemetery. Although nearly every trace of this pioneer cemetery has been erased, about twelve burials have been identified through written records. First used in the summer of 1848 for the burial of the 18-month-old son of Peters' Colonist John B. York, the cemetery was named for a later owner of the property, Eli Mitchell. Among the Tarrant County pioneers buried here are John York, who became a County Sheriff, and Seaborne Gilmore, a Mexican War veteran who was Tarrant County's first elected County Judge. The historic cemetery is a significant part of the area's heritage. Sponsored by the North Fort Worth Historical Society. 1984 #3422
