I checked out that sight that he recommended (public profiler/gb names). It's a cool site. It allowed me to type in my surname (Weatherhead). Then I could choose between two different maps of the UK. One in 1881, the other in 1998. When you click on to one or the other map, it shows the counties/regions where your surname is concentrated, in those given years. I knew, for instance, that my ancestors came from Berwickshire, Scotland, and the 1881 map reflected that, but the strongest concentration of Weatherheads was in Harrogate, in northern England. There was also a cluster of them in north London. Anyway, thanks again for the tip. I recommend this site, as well. ( I just tried to save the images in my computer, but it doesn't save them. I wanted to attach it to this post. Oh well.)
