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.
That's why the Queen Of England visited it yesterday.
The Virginia Company, while not finding the gold or the passage to the Western Ocean they expected, did however make a profitable crop out of tobacco, begin converting natives to Christianity, and keep the Eastern Seaboard out of Spanish hands. They nearly perished several times, but after Jamestown, England had a permanent presence on American soil. Some say that the Plymouth colony actually profited from the experiences of Jamestown.
