[nominative etymology] There's a place called Kenovay on the island of Tiree, which looks like a phonetic rendering of its Gaelic name Ceann a’ Bhàigh, which means "head of the bay", or Bayhead ("the parst of a bay most distant from the larger body of water with which it is confluent"). There are a couple more Ceann a’ Bhàighs and Bayheads in the Hebrides. So that could be the origin of the name.
[blame] Turned out the issue was that ā, entered directly from the keyboard, apparently upsets mc5 to the point where it can’t even. It works over at Dan’s place.
