The Kincaids are said to descend from
the ancient Earls of Lennox, the Galbraiths of Buthernock, the
Grahames and the Comyn Lords of Badenoch. Their name appears to
be territorial in origin, but its derivation is uncertain. One
explanation is that it comes from the Gaelic, ‘ceann cadha’,
the ‘steep place’ or ‘pass’. A second translation
may be ‘of the head of the rock’, and a third possibility
is, ‘the head of the battle,’ which could refer to
a later achievement in the family history.
