:::::::::::Until 2005, virtually all sources on Pictish history indentified Fortriu with Strathearn, with little evidence, just because some authority had once said, "It must be here".  The same is the case with all those who say Aeron is Ayrshire; no one offers a reason for it.  I'm not saying I have proof of a negative, I'm saying that none of them who make that claim have ever offered any evidence to back it up, none, zero, nada, zilch, squat.  It's an embarassment to them, and it's an embarassment to have it in this article.
