For sure, Wallace. What I was trying to say was that genealogy is a science and it can be hugely frustrating for anyone if he mixes that up with sept-attachment. There's a heap of evidence supporting a Cattenach origin in Badenoch, and probably Lochaber, even before they appeared in Dee-side/Don-side in the early 15C (see my post 22 in this thread). That makes your attachment to Clan Chattan a foregone conclusion. But for someone with the name Gow, for example, the lists claim it to also be of Clan Chattan. There was a family named Gow in Badenoch, but the name is simply Gaelic (gobha) for smith and most glens had one of those. How frustrating for a Gow to spend years believing he is a Macpherson, only to successfully trace his ancestry to Argyll or Caithness!
