Could someone please access a 1841 UK census record please? I have all the info you will need to find it!?

Hi I'd love to see this census record but my subscription to census records has ran out!

I've found the record on findmypast.com and 1901censusonline.com I just can't view it. For some reason I can't find it on ancestry.co.uk.

Anyway I'm looking for Mary Langley born 1831. She was living in Huntingdon in 1841. On the findmypast.com record, the right one is the one that says St Neots, Huntingdon. On 1901censusonline.com the entry is the one that says "Huntingdon, Oundle, St. Neots & Thrapston".

It might help you to know that her father was called Isaac Langley,

Please help me, I would love to know where exactly she was living, and what her mother and siblings wer called.

Thank you so much!
