Many early Shelby pioneers came from Frederick, Co. Maryland. The 1790 fs (Frederick Co. only) is now on line. See below. It has surname indexes linked to the original numbered census pages. Unfortunately, most 1790 census takers listed heads of households in alphabetical order, then added people missed or reported. All of the deciphering of names have been done for us!. Enjoy.
