I ran the six surnames I know in my family and only one was a recognised name by the site I used. Hummph!
I tried the Ancestor.co.uk site, but they want euros. Apparently, there are/were some ancestors somewhere in the UK, since the 1851 census lists 4 people with my surname. The England/Wales birth register lists 3 births between 1984 and 2004. The most interesting thing I can almost see without paying for it is between 1871 and 1891, the census figures for that surname went from 23 to 15. During that time span, my great grandfather and his eight brothers emigrated from the UK to Kentucky.
