Siol Alpin
Siol Alpin (from Gaelic, Sìol Ailpein: Seed of Alpin) is a family of seven Scottish clans able to trace their descent from Alpin, father of Cináed mac Ailpín, King of the Picts, of whom the Scots tradition considered the first King of Scots. The seven clans that make up Siol Alpin are: Clan Grant, Clan Gregor, Clan MacAulay, Clan Macfie, Clan Mackinnon, Clan Macnab, and Clan MacQuarrie.
Historical examples of a Siol Alpin tradition
There are several historical examples that show the strength of the Siol Alpin tradition.
Clan Gregor and Clan Grant
The Siol Alpin tradition was so strong in the clans Gregor and Grant that in the early part of the eighteenth century the two clans met at Blair Atholl to discuss re-uniting them. In the discussions, which lasted fourteen days, it was agreed that if the proscription against the surname MacGregor could be reversed then the new clan would take that name, otherwise MacAlpin of Grant would then be used. On the issue of the chiefship of the combined clan there was disagreement, and discussions eventually broke down. Though several Grants, including the Laird of Ballindalloch, "showed their loyalty to the ancient kinship by adding the MacGregor patronymic to their name".
