That is certainly a possibility, but I feel stuck at the moment.
I can't find baptisms for Patrick on the cd [ManxNoteBook] am I being daft or have they not been included?

And until I can find out whether or not Wm had a brother Thos or if his father was Thomas I just don't know.
Don't think I can do any more until I can have a look at the deeds and then try and comprehend exactly what they mean.
The areas that you mentioned ? Arnicarningan and Ballacartoile in Close More ? Are they known as Patrick particles by any chance? Forgive my ignorance but I haven't got access to necessary info to check.

There are also some Quines at Kennaa I think just to throw a spanner in the works !!
Thanks as always Frances
