y-DNA has been a bit of a game-changer for the Shankland study . . since the person who started the one-name study (my husband) has turned out not to be a Shankland after all but probably descended from an Irwin / Irving / Irvine line! And the Irwin / Irving / Irvine line apparently has an NPE or two in it as well. Is illegitimacy inherited?

I imagine there are NPEs in every surname DNA project. It would be much more surprising to find a project without any NPEs. I've yet to hear of any DNA project where all the participants have matching DNA signatures. With DNA testing it's always important to combine the results with the genealogical records. Sometimes it can be established through a process of triangulation that the family trees are correct but there has been an NPE in one specific line. This was the case, for example, with the case of Richard III: http://www.bbc.co.uk/news/science-environment-30281333 Turi King, who led the Richard III DNA testing, has also done some interesting research on surnames and the Y-chromosome. You can find further details here: http://www2.le.ac.uk/departments/genetics/people/king/surnames-and-the-y-chr omosome In case it's of interest there is a page in the ISOGG Wiki with lots of information on NPEs: http://www.isogg.org/wiki/Non-paternity_event Debbie Kennett Member no. 4554 Cruwys/Cruise/Cruse one-name study http://cruwys.blogspot.com http://one-name.org/name_profile/cruwys http://www.familytreedna.com/public/CruwysDNA
