Richard Grenville arrived with 100 men and then he returned back to England for supplies. Francis Drake stopped at Roanoke and they returned to England with him. John White arrived at the island and it appeared that it was destroyed and only bones of man were found. Then less than a month later the first English born child was born in North America.
There were 117 colonists sailing to Portsmouth in attempt to make a new colony near Chesapeake bay. John Whites daughter was going to have a baby. Two years earlier there was an attempt that was unsuccessful to make a settlement on Roanoke island. After Richard Grennville basically abandoned 100 men Sir Francis Drake took them back to england. Then 15 more went to england and Grennville went back to get reinforcements. When White went back all he found was bones of one man that was found.
I believe that the colonists traveled to Croatoan island. I think this because when John White returned and saw the words/letters saying "CROATOAN" carved on to a tree that makes it pretty simple to think that they went to Cratoan island since they write on the tree the name of the island. Also, why would they write Croatoan if they did any of the other theories. For example, why wouldn't they write a cross if they were in danger if they were killed by the Native Americans.
