Hello, Looking at the 1911 census, I have a question about the reference numbers that are listed, i.e., RG14PN27195 RG78PN1554 RD502 SD1 ED19 SN12 I assume the PN in RG14PN27195 stands for piece number. If so, why are there two register general numbers along with a piece number for each of them? The ED19 is the enumeration district number, but what are the RD 502, SD1, and SN12 numbers? Thanks for any help. Sandi in the U.S.

Hi Sandi As posted on another forum Census reference If you have precise references for a census page you wish to view, you can go straight to that page by entering the references into this field. Census references can be entered in any order, but the prefix (RG, PN, RD etc.) must be included. Each reference should be separated by a space. For example: RG14 PN8600 RG78 PN445 RD167 SD3 ED11 SN200 A key to the references is below: RG14 - this is the reference for household schedules. RG refers to the Registrar General series of records held by The National Archives (TNA). RG78 - is the reference for the enumerators' summary books. PN - is the piece number within RG14 or RG78. RD - is the Registration District number. SD - is the Registration Sub District number. ED - is the Enumeration District number. SN - is the Schedule Number within RG14.
