In the parish of Blair Atholl, Scotland, until the 1790s there was a small clan in Strathtummel known as "Calmanach". The name was taken from a St Colman, who came to Strathtummel in the 7th century. A hamlet, now all in ruin, was known as Coróchalmaig or St Colms corrie, and the burn passing through it bears the name of AltóChalmaig (Aldcharmaig is to the west of Bruchbane). The people were dissatisfied with the name and, having ascertained that it meant a dove, they turned the Gaelic "Calmanach" into the Scots "Doo". It is spelt "Dow", and though usually correctly pronounced "Doo" in Atholl, it is generally pronounced elsewhere as it is spelt and so the meaning is lost. McColman from the same area is the same geneeral family.
