given the co-ordinates for "Linne Loiny", I'd say it was meant to be the cairn which is known as Pontius Pilate's Grave. Now I will attempt to clarify the various things in that field!

Bridge of Lyon long cairn (NN 7296 4655)

just a long cairn

Bridge of Lyon standing stones (NN 7314 4641)

one stone still standing, with one possible fallen one beside it

Lyon Bridge cairn (NN 7317 4657)
http://www.themodernantiquarian.com/browse.php?site_id=2332
the remains of a cairn which legend has it is the grave of Pontius Pilate, which has a long cup-marked stone on it, believed to once have stood upright

the "Roman Camp" is actually a medieval moat:

hope that clears up any confusions about what's what!

ps - I'd be happier too if the Fortingall & Kenmore grouping could be split. I don't really think Kenmore Church and The Appin of Dull cup-marked rocks should be lumped in with Fortingall
