The settlers at Jamestown had much worse luck than many others. Plimouth had its own 'starving time.' A third died-- but they were resupplied better, and had support from the local Wampanoag people. The people at Roanoke vanished, but there are no signs of violence or force. They may have been absorbed into the local populace. Earlier settlements at Ft Caroline, and St Augustine, even managed better survival.
'The Tempest' was supposedly based on Jamestown.
Anyway-- here is the link. There is also a facial reconstruction of the girl they are calling Jane. She is ordinary looking. She looks like someone we might know-- makes it sadder, to me.
