On the date April 26, 1587, around 117 people tried to establish the first English settlement in America. The goal for these 117 people was to create a new colony near the Chesapeake Bay.
Two years after the arrival, an unsuccessful attempt of establishing a colony in Roanoke was made. The colonists were running out of supplies, so Richard Grenville left to get more.
I believe the colonists simply traveled to Croatoan Island. One reason is, in the carving there was no cross meaning they weren't in danger. The second piece of evidence is that Croatoan Island was already familiar to them, and they knew how to get there. My last reason is that John White never made it to the island, so they could have been at Croatoan Island, and White never made it there to find out.
