I've been browsing the 1851 UK and Ireland Census on Ancestry - I was first taken there with a specific person in mind, but then began to look generally at surnames and had a slight bit of success but I've been trying to find a family named Milsop or similar and finding no one of that name at all, yet I know there were people by that name in Ulster at the time. So I checked here and went to the Irish site above but nothing - no one. It seems odd.
Was this census completed or is it just a few spots here and there?
