What does the name Murdach mean?

The western seacoast of Scotland and the rugged Hebrides islands made up the ancient Kingdom of Dalriada, the ancestral home of the Murdach family. Murdach is a name for a person associated with the sea. The name Murdach derives from one of two Gaelic names which have become indistinguishable from each other. The first of these, Muireach, means belonging to the sea or a mariner. The second name is Murchadh, which means sea warrior. 1

Migration of the Murdach family

Numerous Scottish settlers settled along the east coast of the colonies that would become the United States and Canada. Others traveled to the open country of the west. At the time of the American War of Independence, some remained in the United States, while those who remained loyal to the crown went north to Canada as United Empire Loyalists. The highland games and Clan societies that sprang up across North America in the 20th century have helped many Scots to recover parts of their lost traditions. Research into passenger and immigration lists has revealed some of the very first Murdachs to arrive in North America: John Murdoch settled in New England in 1718; John Murdoch settled in North Carolina in 1774; Robert Murdoch settled in New Hampshire in 1718; Jeremiah Murdock settled in Virginia in 1726.



The Murdach 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: Omine secundo
Motto Translation: With favourable omen.
