Just to give you a heads up I have just noticed that the 1861 census for Surrey > Witley > District 4 > 21 original is not matching the info in the Ancestry index box at the bottom. Here is a link to the page to see what I mean http://search.ancestry.co.uk/iexec?htx=view&r=5538&d...
If you look at the image and then the text that is in the box below they don't match up. They are not the correct names, and the simple male/female count is different. I have gone through the whole of this document and it is an issue all the way through. Just looking at the first 2 pages where the census summary is the box at the bottom is listing people as if it were a normal census page. Not sure if this is happening throughout the 1861 census, but worth double checking.
I have reported the error via the report a problem button but it is just a simple drop down box and doesn't really allow for the detail I have given here. I have contacted the support email address as well, but it appears that just relates to IT issues rather than this type of thing. Hopefully it will be sorted soon.
