Almost twenty years later a different group of English did sail to the Chesapeake and start a settlement. It was called Jamestown and one of its' leaders was Captain John Smith. He claimed that he had killed them all to discourage other English from coming to the New World and taking the Natives' land. Captain Smith believed it and some historians today think it happened but again, there is no proof. Now it's your turn.
Settlement just means a place where people live, especially a new place.
The people of long ago used another word for the same thing, 'plantation'. The people who went to live there were called planters. It didn't mean that they were all farmers who planted crops, although many did. Later in American history large farms, especially in the South, came to be called plantations and the people who owned them were called planters. Most people in the United States speak English because most of the earliest European settlers were from England.
