The add ons, to the originals, are interesting.
The regional surname tool looked useful, and different from that on line, which maps 1881 or 1998 distributions on to a map of postcodes (rather than counties). Seeing Lisa's surname distribution was especially interesting since I have cousins of that name, who come from the centre of that concentration of the name.
The second story was also of interest as we knew a German, also from East Prussia, who had settled in Berkshire after his time as a POW. Although he married an Italian rather than English girl.
