If you share one of these surnames, especially some of the rarer ones, we'd be interested in hearing from you. The more surnames you share, naturally, the closer you are likely to be related.
For the first four generations, the geographical location is mostly Missouri. Then it starts to disperse, ultimately arriving in French Canada, Ireland, Scotland, Norway, Germany, Netherlands, and England.
