John White, the governor, and the colonists sailed from Portsmouth, England to the New World to establish a new colony near Chesapeake Bay. White's daughter, Elinor, was married to a man named Ananias Dare and was expecting a baby during this time. They arrived at Roanoke and started to build their colony.
John White's daughter, Elinor, had her baby and named her Virginia. The baby was the first English child born in North America. Then John White decided to return to England to get some more supplies. He told the colony to carve the name of the place they were going on a tree if they left Roanoke Island. He also said to put a cross under it if they left because of danger.
I think the scenario that most likely happened was Scenario #1. 3 pieces of evidence from the text is that 1) The Roanoke colony was safe with in Croatoan with a man named Manteo, an Indian from Croatoan who had been to England twice. 2) The Hatteras Indians, who lived on or frequented Croatoan Island, tell us that several of their ancestors were white people. 3) The Roanoke Island carved the words "CRO" and "CROATOAN" because they left to Croatoan, and John White told the colonists to carve the name of the place they will travel to on a tree.
