What does Dun a Dalaigh refer to?  The only thing coming up in a web search is some holiday cottages located in Annagaire about 20km south west.

The Aspick River appears to be mislabeled.  According to the GSGS3906 map, it is actually the Gleanna River.  About 5km south, the Aspick River joins the Gleanna River.  The map showed it reverting back to the Aspick River (and reverting back to a stream) about 1500m south. I've changed this so the Gleanna River is so named as far as the sea.
