They came for a little while and then disappeared. I’m not sure they left anything behind. Later settlements in Virginia appear to be do overs. Is there a legacy from Jamestown? Clearly the Pilgrims left behind a legacy including the written record and enduring institutions.
I believe you're thinking of Roanoke. Jamestown was actually the beginning of the permanent English presence in "Virginia", and it was from this colony that all of the others in the region grew.
Their contribution was not just significant. It was earth-shaking.
Jamestowne boasted the first factory in North America, the first permanent English settlement, the first inter-racial marriage (Pocahontas), the first attempt at Communism as a form of government(quickly abandoned), etc., etc. How can you say that they left no record?
Jamestowne wasa fully functioning commercial enterprise that later became a full fledged Colony — long before the Pilgrims ever left England. Jamestowne pioneers did not “disappear”.
My family can trace its roots to the First Supply. My ancestor came with Lord De La Warre.
Have you ever visited Jamestowne? Not the reconstructed village, but the actual site of the original settlement? I visited there in July one year about 10 years ago. It was so blasted hot and humid and buggy that I do not know how those first settlers survived the first SUMMER. I couldn’t breathe, and I have no idea how they managed to put their gardens in, much less work on them!
