Are you suggesting that the English settlers who vanished from Roanoke Island went native in the same way that sailors of the Bounty went native on Pitcairn Island?
Thats an interesting hypothesis and one I havent heard about before.
It does make some sense in that the desire for survival is a strong force among all humans and the natives may not have objected to their assimilation and could explain the reason for the lack of human remains at the settlement site.
But aside from some native Indians with surnames from the colony's roster and antidotal suggestions that some Indians looked more like Englishmen, what is the archeological or anthropologic evidence to support this hypothesis?
The English settlers who vanished from Roanoke Island could have just have reasonably died from a combination of starvation, disease and Indian raids.
The issue of surnames, if adopted in later times can be explained as having nothing to do with the original settlers as well as inter marriage among later English and natives could explain the English looking Indians. It could be a more recent phenomenon and not related to the original settlement.
Interesting theory though.
All true, but the individual Indians that looked like Englishmen observations were made in the first years of Jamestown. After 20 years the few Roanoke adult survivors would likely all be dead just because living "native" in those environs meant generally that a thirty year old was a respected elder and a 60 year old was next to mythical.
