English: from the Middle English personal name Elwald, Elwold, Alwold (Old English Ælfweald, ælf ‘elf’ + weald ‘rule’). The surname is now rare in Scotland, but was once quite common in the Scottish borders where it was altered to Elliott and Ellett . The different surnames may have co-existed and become confused with one other.
