Hi Jim, I too went to The Rhaa about 4 years ago and was invited in to the new farmhouse by the Kellys'. Would be interested to see any info you have about the Kneales you mention.
Just to make sure its the same place, coming from Douglas direction you take the turn - a small lane - before the one to Lonan village, and its a little way up on the right. The land owned by the Kneales streched from there up to just before the Churchyard at Lonan.
Regards

Laurence
