Norse-Gael in the context of Cotter family

The Uí Ímair (Irish: [iː ˈiːwəɾʲ] ; meaning ‘scions of Ivar’), also known as the Ivar dynasty or Ivarids, was a Norse-Gael dynasty which ruled much of the Irish Sea region, the Kingdom of Dublin, the western coast of Scotland, including the Hebrides and some part of Northern England, from the mid 9th century.

The dynasty lost control of York in the mid 10th century, but reigned over the other domains at variously disputed times, depending on which rulers may be counted among their descendants. This has proved a difficult question for scholars to determine, because reliable pedigrees do not survive. Additionally, for between three and four decades, the Uí Ímair were overkings of the Kingdom of Scotland itself, distinct from the Kingdom of Strathclyde, of which they may also have been overkings, and later briefly the Irish province of Munster, dominated from Waterford, and later still, briefly the English kingdom of Mercia. In the west of Ireland, the Uí Ímair also supplied at least two kings of Limerick, from which they may have attempted to conquer Munster again.

Clan MacDougall is a Highland Scottish clan, historically based in and around Argyll. The Lord Lyon King of Arms, the Scottish official with responsibility for regulating heraldry in Scotland, issuing new grants of coats of arms, and serving as the judge of the Court of the Lord Lyon, recognizes under Scottish law the Chief of Clan MacDougall. The MacDougall chiefs share a common ancestry with the chiefs of Clan Donald in descent from Somerled of the 12th century (and thus further of the Viking-born Norse-Gael dynasty of House of Ivar). In the 13th century the Clan MacDougall whose chiefs were the original Lords of Argyll and later Lords of Lorne was the most powerful clan in the Western Highlands. During the Wars of Scottish Independence the MacDougalls sided with the Clan Comyn whose chiefs rivaled Robert the Bruce for the Scottish Crown and this resulted in clan battles between the MacDougalls and Bruce. This marked the MacDougall's fall from power and led to the rise of their relatives, the Clan Donald, who had supported Bruce and also the rise to power of the Clan Campbell who were then the habitual enemies of the MacDougalls and later of Clan Donald.

The MacDougalls supported the House of Stuart during the Scottish Civil War of the 17th century and during the Jacobite risings of the 18th century.

Clan MacLeod (/məˈklaʊd/ mə-KLOWD; Scottish Gaelic: Clann Mhic Leòid [ˈkʰl̪ˠãũn̪ˠ vĩçkʲ ˈʎɔːtʲ]) is a Highland Scottish clan associated with the Isle of Skye. There are two main branches of the clan: the MacLeods of Harris and Dunvegan, known in Gaelic as Sìol Tormoid ("seed of Tormod") and the Clan MacLeod of Lewis Assynt and Raasay, known in Gaelic as Sìol Torcaill ("seed of Torcall"). Both branches claim descent from Leòd, a Norse-Gael who lived in the 13th century.

Today, Clan MacLeod of The Lewes, Clan MacLeod of Raasay, and Clan MacLeod are represented by "Associated Clan MacLeod Societies", and the chiefs of the three clans. The association is made up of ten national societies across the world including: Australia, Canada, England, France, Germany, New Zealand, Scotland, South Africa, Switzerland, and the United States.
