He further states that the Sykes surname could have had a single founder because in the number of generations the surname Sykes has been in use, 50% is about what would be expected with a 2-2.5% NPE rate. So if your surname project is open to all users of that surname, it should be expected that there will be multiple lineages. It would appear that identification of NPE's would be an objective of a project, unless membership was restricted to documented descendants of a single or select group of progenitors. I have invited two personal friends of different surnames, who do not know there genetic surname due to NPEs, to join our project while waiting for  a DNA match that would identify the true surname.  We have one member who discovered his Y-DNA did not match a known paternal line cousin. It was then revealed that the other side of the family knew that his grandfather had been born to an Oakes, out of wedlock, with an unknown father, and given her surname He was very fortunate to find an exact match to a family that lived near his great grandmother and has been accepted as a member of that surname project.

Yes, I have done the same; that is, allowed someone into my project, just to get the price discount, because their "biological" surname is unknown. There is also an "Adoptees" group at FTDNA set up for this purpose: https://www.familytreedna.com/surname_join.aspx?code=T42871&special=true FTDNA says (somewhere on their web site) the number of customers tested who get an "unexpected" result is about 2-5%. It's been running *at least* that much in my projects. Just as we warn novices not to do their genealogy if they can't deal with discovering something they'd rather not have know, the caveat is in spades for being DNA tested. It's one reason I suggest people not mention being tested, even to family members, until after they've seen the results.
