DH's daughter has very kindly sent us a belated Christmas present ...

[Carla]

... a hefty tome of a Chronicle of our family name. And in the back, where all the people who share our name is listed, we're there complete with our address!! How on earth did they do that!!

Electoral register data Carla. You can opt to be listed in one of two ways when your council do the annual update, and asking for a restricted listing (cannot remember the actual correct term for this) means your address is not published in any publicly accessible form of the completed register. A godsend and introduced to stop abuse by mail-order companies, stalkers etc.
