Wallace

Scottish and northern Irish: from Anglo-Norman French waleis ‘Welsh’ (from a Germanic cognate of Old English wealh ‘foreign’), hence an ethnic name for a Welsh speaker. In some cases this clearly denoted an incomer to Scotland from Wales or the Welsh Marches, but it may also have denoted a Welsh-speaking Scot: in western Scotland around Glasgow, the Welsh-speaking Strathclyde Britons survived well into the Middle Ages.
