Matrilineally, I assume, otherwise you'd also be related to the CEO. Pretty cool stuff. I was attracted to this as I'm an amateur genealogist, but have an awfully common name and descend from a line of poor record keepers.

I fell in with an internet group who is researching Williamses from eastern KY (where my ancestors may have come from) and we're all looking forward to the results and encouraging any Williams men to participate (just Y chromosome stuff for now). The possibilities of proving and/or disproving certain traditions and family lines is compelling. But, as one researcher pointed out, the y chromosome test is only as 'good' as your female ancestors.

Recently an unrelated Williams group who's testing got an unusual surprise: a complete match from someone named Wright. Research indicated that these two families had lived next to each other and had even migrated together to another state (several generations ago). They are currently searching for the descendants of earlier generations to find out whether there's a Williams or a Wright in the woodpile. FTDNA is calling it an 'event'.

This stuff is fascinating.
