The Kingdom of Galloway was a Norse-Gaelic Kingdom in the middle ages and would emerge after a Norse Gaelic migration to the region and it would cause the establishment of the kingdom by Suibne mac Cináeda the first king of Galloway over lands that may have been under control of the Kingdom of Strathclyde previous to its establishment.

....

I cant determine if the end of the kingdom and beginning of the Lordship was when it was split between Lochlann (Roland) and Donnchad (Duncan) or after the collapse of the Fergusean Dynasty's power and incorporation into scotland due to the Galloway revolt of 1234–1235 (after some further research it was around the time of the split because the kings of England and Scotland help make the divide so they were subjugated and at that point firmly incorporated into the kingdom of Scotland as the Lordship of Galloway)
