I am doing a world wide One Name Study on Catanach and all variations.
My husband is descended from a George Catanach of Montrose and back in time to an Alexander Catanach.
When one follows the certificate trail, the name is spelt in a variety of ways.For instance, my husband's great grandfather was born as a Catanach, married as a Cattnach, but managed to die as a Catanach.Hisgggg grandfather was spelt Catanach, Cattanach and Catnach!
The correct spelling has been lost over time.The pronunciation in Scotland is Catanaaaah (long soft sound - not Catanack, as many pronounce it.
Officialdom has always had difficulty understanding a Scottish brogue, particularly those emigrating from the Highlands and most Cat(t)anachs emanated from the Highlands around Inverness, Perth and Forfar.
Anyway, we are all part of a wonderful family and, as part of that family, if I can assist you in any way, please don't hesitate to ask, I will be only too happy to do so.
