I just emailed the pic to 4W's and was going to mail again to see if he knew where 'Bocan' was on P56/57 'cos it has very interestingly shaped stones, after searching here I found: http://www.themodernantiquarian.com/post/28619 almost an exact replica of the photo in the book except the house is more in view! Have to pencil in another trip to Donegal now...
