Hi,
I'm pretty experienced re: Ancestry, Findmypast, digitized newspapers and archive centres. I'm struggling here too. I've have never needed to search for a census page by its reference numbers but am now trying to do just that and find the debtors prison in Whitecross Street in 1841. I have found the NA page 'Your Archives' via Valda's link (thanks) and the entry for the prison therein. Here is what it gives:
Reference: HO 107/727
Book: 12
Folio: 1-11
I had no problem finding the Ancestry page to enter these details but nothing I do seems to get me to what I want. I'm getting closer by entering 'East London' as the registration district and 'Cripplegate' as the sub-registration district (without that it was hopeless with hits from round the country!).
Valda, if you get this message can you possibly, line by line as per Ancestry's 1841 Census page, tell me what to enter and also confirm that you've done it yourself and you personally have gotten to the Whitecross prison pages.
Many thanks
Paul
