Hurtle Mills was incorporated in 1892 with the town being given the name in 1852 when the Hurtle Family bought the mill. It straddles the southern county line of Person County and northern Orange county. Person county is today considered Hurtle Mills "home county". So you should look for records in Person and Orange County.
