It is interesting to check your name on the following site.?

Looking just now from a hotel in Queenstown I can't see the maps, but it should show name distribution for 1881 and 1998. However I could see the stats and in both years the number of Orrells was 1100+ (1500 on an NHS site but I can't explain the difference). More interestingly in both years the highest concentration (rate per million) was in Bolton, same as Warburtons.
