On the western coast of Scotland and on the Hebrides islands, among the ancient Dalriadan clans, lay the roots of the MacOnachie family. Known as the Clan Donnachaidh, (MacDhonnchaidh) 'son of Duncan' the family's origins are very distinguished, as the senior branch of the line were the hereditary abbots of Dunkeld, who traced their descent from Iona. In addition, Abbot Duncan of Dunkeld, the Robertson progenitor, was killed in battle in 964, as he led the warriors, bearing, a reliquary of St. Columba. His grandson, Abbot Crinan of Dunkeld, married the Kings daughter and then fathered King Duncan I of Scotland who was killed by MacBeth (of Shakespearean fame). Crinan is buried at the Isle of lona, burial place of Scotland's early Kings. [1]

Early Origins of the MacOnachie family

The surname MacOnachie was first found in Atholl. King Duncan's younger son, Maelmore, sired Madadh, Earl of Atholl, and his grandson, Earl Henry, was father to Conan who held vast territories in this area. Conan of Glenerochie was the first Chief of the Robertsons and gave his name to the Clan Connchaidh or Duncan. His successor, Duncan, the 5th Chief, led the Clan in the army of King Bruce at Bannockburn in 1314 against the English. For this service, and his subsequent staunch support of the Scottish Crown, his grandson Robert of Struan was granted the lands and barony in 1451.

The MacOnachie Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Virtutis gloria merces
Motto Translation: Glory is the reward of valour.
