This Donegal name is from MacColl, Gaelic Mac Colla, the name of a galloglass family introduced there from Argyllshire in the sicteenth century.  Colla was a Gaelic personal name and Colla Uais, a semi-legendary Irish king of the fourth century, is claimed as the great ancestor of the MacDonalds.  The MacCalls or MacColls, long settled in Argyllshire, were of the race of Clan Donald but in practice followed the Stewarts of Appin.  Although of no connection with the Ulster MacCalls or MacCauls, there has been some intermingling of the two names (see MacCall).
