English (Durham and North Yorkshire): habitational name from Walburn in Downholme (North Yorkshire). The placename probably derives from Old English wala, genitive plural of walh ‘foreigner, Briton, serf’, + burna ‘spring, stream’. Alternatively, the name may derive from the Old French personal name Walebron, perhaps itself from ancient Germanic Waldbrand (wald ‘power, rule’ + brand ‘sword’).
