2. DNA research continues to give evidence that all the relevant surnames have a common ancestry, as well as fascinating hints that they all seem to descend from a member of the "de Lancastre" family who ran the area around Satterthwaite for more than a century in the 1100s and 1200s.
BUT we still do NOT have anyone with the Sutterfield spelling. Indeed, we also can't yet compare the Satterfields (probably cousins of the Sutterfields with a variant spelling) on all the markers we'd like to.
The DNA project (http://users.skynet.be/lancaster/Lancaster.htm) is run by its member families (no hard work involved!) and let's hope we can get two families for each variant spelling. Any takers?
