as country. "The generic term of _Scoti_
embraced the people of that race whether inhabiting Ireland or Britain.
As this term of Scotia was a geographical term derived from the generic
name of a people, it was to some extent a fluctuating name, and though
applied at first to Ireland, which possessed the more distinctive name
of Hibernia, as the principal seat of the race from whom the name was
derived, it is obvious that, if the people from whom the name was taken
inhabited other countries, the name itself would have a tendency to pass
from the one to the other, according to the prominence which the
different settlements of the race assumed in the history of the world;
and as the race of the Scots in Britain became more extended, and their
power more formidable, the territorial name would have a tendency to fix
itself where the race had become most conspicuous.... The name in its
Latin form of Scotia, was transferred from Ireland to Scotland in the
reign of Malcolm the Second, who reigned from 1004 to 1034. The 'Pictish
Chronicle,' compiled before 997, knows nothing of the name of Scotia as
applied to North Britain; but Marianus Scotus, who lived from 1028 to
1081, calls Malcolm the Second 'rex _Scotiae_,' and Brian, king of
Ireland, 'rex _Hiberniae_.' The author of the 'Life of St. Cadroe,' in
the eleventh century, likewise applies the name of _Scotia_ to North
Britain."[5]

A strong immigration early set in from the north of Ireland to the
western parts of Scotland. It was under no leadership, but more in the
nature of an overflow, or else partaking of the spirit of adventure.
This was accelerated in the year 503, when a new colony of Dalriadic
Scots, under the leadership of Fergus, son of Eric, left Ireland and
settled on the western coast of Argyle and the adjacent isles. From
Fergus was derived the line of Scoto-Irish kings, who finally, in 843,
ascended the Pictish throne.

The inhabitants of Ireland and the Highlands of Scotland were but
branches of the same Keltic stock, and their language was substantially
the same. There was not only more or less migrations between the two
countries, but also, to a greater or less extent, an impinging between
the people.

Ulster, the northern province of Ireland, is composed of the counties of
Antrim, Armagh, Cavan, Donegal, Down, Fermanagh, Londonderry, Monaghan
and Tyrone. Formerly it was the seat of the O'Neills, as well as the
lesser septs of O'Donnell, O'Cahan, O'Dohe
