I have purchased a couple of census cd's from HFHS which details Surname, Fore Name, Age, Parish District and Folio Number. I was wondering how the Folio Numbers work (example = 727a) and whether I can use the number to purchase the actual fiche to discover further information like address and possibly occupation? I assume Fiches described as index's won't give the additional information I an looking for? Thank you for any help given
