This site is an interesting adjunct to my previous note on geneaology – the surname profiler from UCL lets you compare the geographical distribution of a given surname in the UK between 1881 and 1998.
I did a quick test using my surname (Elve – or as it was commonly spelled in 1881, Elvey). The 1881 result looks familiar from the 1881 census research I have been doing as part of finding my ancestors:
The 1998 map is less useful – even though the spelling I use (Elve) is reasonably well-established, there is no mention of it in the database. So for 1998 I again searched on the “Elvey” spelling.
Nevertheless an interesting site.
