Dynastree maps out your last name

If you've ever wanted to know where there might be others with your same last name, you can now find out with Dynastree's free search tool.

Dynastree (formerly has a new tool that shows you where others with your last name live. You simply type in your name and it shows you on a state-by-state basis where there are others who share it. Of course if your last name is "Smith" or "Jones" this won't help much, but I found it to be spot on with mine.

Besides the U.S., which has approximately 1.7 million last names in its database, you can also search all of Canada. Included with both is a small analysis right below the map that ranks your last name's prominence in each state (or province/territory), as well as on a national level.

Where the tool won't help you is tracking some of these folks down, or helping you figure out if you're actually related to them. That, to me, seems like the next logical step.

One other thing to note is that I didn't have any luck getting this tool to run in Firefox or Google Chrome. However, it worked fine in Safari and Internet Explorer.

Donald Trump isn't the only Trump in the U.S. Dynastree can now search for your surname as well. CNET Networks
