How did Leswalt in Scotland get its name?

There are two possibilities, although no one is certain of the origin. The first possibility is that it is taken from llys gwellt (Welsh) which means grass court, and the second is it is derived from lios uillt (Gaelic), meaning fort of the glen. Both origins have merit since Welsh and Gaelic was spoken in the region. Galloway actually means "land of the stranger Gaels" and is likely a reference to the area being Welsh speaking, rather than the more common Gaelic.
