Thurman

English (East Midlands): from the Middle English personal name Thurmond, Old Norse þormundr, composed of the elements þórr, name of the Norse god of thunder (see Thor) + mundr ‘protection’. Reaney and Wilson suggest that, Thurmond having been an uncommon personal name, this surname may also represent the commoner name Thurmod, Thormod with the second element derived from Old Norse móþr ‘mind’, ‘courage’, but assimilated to -mund (a common second element in other compound names).
