I uploaded my Y-DNA results to ysearch.org. Any male Wilton decendents relating to the Wiltons of Cornwall c.1450 will have the same results of mine, as the y-chromosome is passed down from father to son unchanged.
Click "search" on the first two pages, and the list of people with various surnames, are related within approximately 50 generations, which is interesting because "prima" Wilton, likely had brothers etc. who became the ?? (surnames).
If you want to know if you relate to this family, then you should order a kit($100) from the Genographic Project at the National Geographic website.
