Who were some of the people that were important in the founding of jamestown?

Captain John Smith: One of the original settlers, the one with most experience, a leader of the colony, led numerous exploration expeditions
Chief Powhatan: He helped the people of Jamestown numerous times, including feeding them throughout the winter
Pocahantas: She saved John Smith once, and remained as the 'middle man', settling disputes between the two people groups

these are just a few

hope this helps
