I for one would be interested in the Cd, or where to get a copy.Maybe needs a bit more exploring. If the CD I mentioned would be helpful to you (or anyone) let me know - it shows how many of that surname (e.g. 1-10; 10 - 100 etc) by county so useful to see where they most like were at the time (or rule out where they're not). I'll stop now as this doesn't make much sense, but the offer of a lookup is there.
