JayMan in Jayman’s Blog which focuses on Human BioDiversity (HBD) has recently been writing a series about clans, clannishness and where the people in these groups came from. His focus has really been on differences between groups of people, but it occurs to me that this information can also be used in reverse. For example, if your ancestors are found in a particular location, you can use these tools to perhaps gain some insight into their origins, or at least where you might want to first look, and why.
Let me also say that exceptions are always possibilities. For example, my line of Estes family came from Deal in Kent and settled in Virginia. But one of my Abraham Estes’s cousins did settle in New England. So take a look and enjoy.
There’s a Facebook Group for Surname Distribution Mapping as well you might want to follow.
