You can also try http://www.bt.com/phonenetuk/ which allows you to run a search on a surname,address, etc. You'll also need to enter a location/area name for the search, but this can be wildcarded and is in fact quite wide. A search on the Clifford surname in Enniskillen turned up only one Clifford in Enniskillen but 21 in total in various other towns(Belfast, Londonderry, etc). JB
