Etymology

'Stream of the beggars,' v. lacu , probably a name of contempt, the first element being the OE  loddere , 'beggar.' Cf. Lotherton (PN D 262) and Loderswel in London, c. 1200 Loddereswell (Stow's Survey ed. Kingsford ii, 272). Leatherlake Ho is identical with the present Runny Mede Ho, and the name referred to the tiny streamlet here, forming the boundary between Berks and Surrey.
