Saxon Merton
The Saxon name ‘Merton’ is usually understood to mean ‘farmstead by the pool’, though an alternative interpretation might be ‘farmstead by the boundary’.
Merton first appears in extant records in a Latin charter of 949 in which King Eadred granted ‘Mertone’ to a man called Wulfric. In 967 King Edgar granted Merton to Ælfheah and his wife Ælfswyth, and this charter includes a description of the boundaries of the estate, written in Old or Middle English. Starting from a ‘boundary pool’ on the Wandle in the south-east of the estate, the boundary markers were a ‘slade enclosure’ on the south, a stream (the Beverley Brook) on the west, passing ‘hoppinge’, a marsh and a ‘rough pool’. On the north was the ‘Wimbledon people’s boundary’ leading to a ‘hop’ or enclosure to the north of the ‘broad ford’ crossing the Wandle. The river then formed the ‘Mitcham people’s boundary’ with Merton, as far as the ‘boundary pool’ where the circuit began.
