Thanks David, that's a really interesting map. It was fascinating to see the relative location of places that keep cropping up in my researches of this line - Ballakinnag, Ballalionney, Berk, Lhergy Vreck, etc. And the corn mill at the end of Glen Wyllin is seriously precarious at that time! I couldn't quite make out if it said what kind of mill it was further up the stream, and the coastal one is close to Kerrowcruin while also being in Glen Wyllin! I'm really looking forward to looking into this further, and this family's land ownership in general in Kirk Michael.

Thanks again for introducing me to these new sources.
