The Overbourn Marshes were located in the Southfarthing, south of the Shirebourn river, where it flowed into the Brandywine river.
The name probably means 'over (across) the bourn (stream)'. Old English ofer means "border, margin, edge" and the element -bourn, common in English river- and place-names, refers to the Shirebourn.
