Gervase of Ebstorf
The connection between Gervase of Tilbury and Gervase of Ebstof can "only remain hypothetical"; the arguments for Gervase of Tilbury being the mapmaker are based on the name Gervase, which was an uncommon name in Northern Germany at the time and on some similarities between the world view of the mapmaker and Gervase of Tilbury.
