I now realise that I left out the all-important word "yet" in my reply above: "The name was unknown in Nottinghamshire apparently and large numbers of my Bousfield ancestors were in Nottinghamshire at the the time of the 1881 census." That isn't quite what I meant. Had I included the "yet", it would have read: "The name was unknown in Nottinghamshire apparently and YET large numbers of my Bousfield ancestors were in Nottinghamshire at the the time of the 1881 census." Slightly different! However, I was luckier with most of my other key families, who were more or less where I would have expected them to be. Interesting, but not surprising, is how the names have spread by 1998.
