If you have common surnames on your family tree, you may have become frustrated at times trying to determine whether the “John Williams” or “Elizabeth Smith” you’re looking at in a record belongs to your John or Elizabeth. Would it make a difference if you discovered they lived in an area where there very few folks by those names during that time period? It would. Furthermore, it would probably also be nice to know things like where else in the world–or within England, for example–that surname is found now (or was in the past).

The enormous amount of census, vital records, and family tree data now online is making it easier to answer questions like these. Below, find free online tools for mapping common surnames (and less-common ones, too) across time. They include surname search tools hosted by a couple of our Genealogy Giants, and What can you learn from the following sites? Do they agree with one another? Check them out!
