Isle of Arran (Scotland, United Kingdom)

Some islands and regions of Scotland seems to be gaining their own unofficial flags in last years. Looking at them, I noticed that the Isle of Arran, the biggest on the Firth of Clyde, is flagless.

The isle has a long and interesting history, much of which I wanted to represent in the flag, following:


A black saltire on white was the arms of the 5th Lord Maxwell, regent of the island (practically, a monarch) for five years in early 16th century. The saltire was turned in a Nordic cross, as the island was ruled by the Kingdom of Norway during the Viking Age. On the canton, a black lymphad with red flags, heraldic augmentation gained by the earls (now, dukes) of Hamilton when they became earls of Arran.

As far as I know, the black Nordic cross on white is currently unused by any entity, at least in United Kingdom.

Comments and suggestions are welcome.
