Glendunning is probably an alternative spelling of Glendinning. They were a lowlander sept of clan Douglas. Clan Douglas was also a lowlander/Sassenach clan. Also "de Glendonwyn". Worthington is definitely not Scottish.
There are two clans Fraser, both were lowlanders originally, but one settled in the highlands in the 1300s iirc.
Copeland was Norse but it's just a place name.
