The surname MacTamhais is the Gaelic
for the more modern spelling of MacTavish.
The Clan
was seated in their Charter lands of Dunardarie where they were
one of the clans known as "the Children of Colla" or "the
children of the mist". The Dalriadic Kingdom of Dunadd is
on Dunardarie Lands.
During the period known as the Jacobite uprisings, the MacTavish
were, as many Highland Clans, sympathetic to placing the Stuarts
back on the throne, as was their right. When Charles Edward Stuart,
better known as Bonnie Prince Charlie, landed on Scottish soil
in July of 1745, some Highland Clans were preparing to join Prince
Charles in his quest to put the Stuarts once again on the throne
of Scotland. .
