Hi,

in case you haven't seen this, and especially if your family's roots were/are in Europe, here's a page that has maps for a few countries:

http://www.verwandt.de/karten/absolut/brandl.html

Alternatively you may enter other names on top of the page and see the results below. There are links for Germany, Switzerland and Poland too on the bottom. Unfortunately in German language only, but a map doesn't need much translation to be understood. May be different with the details that are shown for each name ...

Regards
Tilman
