Bones discovered four years ago at the site of America's first permanent English settlement could be those of Jamestown's unsung founder, a knight or a captain.

A tooth analysis did not rule out that the skeleton is, as Jamestown researchers had theorized, that of Capt. Bartholomew Gosnold, principal organizer of the expedition from England that established Jamestown in 1607. Next year marks the settlement's 400th anniversary.

But test results released Monday also suggest two other possible candidates: Sir Ferdinando Wenman, a knight and the master of ordnance at Jamestown, and Capt. Gabriel Archer, a lawyer who was the first recorder of Jamestown.
