A sept of the larger Ross Clan, the MacTaggart name was originally derived from the Gaelic, “Mac-an-t-sagairt’, meaning,’ son of the priest’. One of the first mentions of the MacTaggart name in Scottish history was in 1215, when Ferquhard Machentagar thwarted a rebellion and presented the leaders’ heads to King Alexander II.
Accoridng to the Chronicle of Melrose, “Machentagar attacked them and mightily overthrew the king’s enemies; and he cut off their heads and presented them as gifts to the new king.”
For this act of bravery, Ferquhard was made Earl of Ross, a position he would hold until his death around the year 1250.
Beyond this, not much is known of the MacTaggart name other than that it appeared in the Dumfries area of Scotland around the 15th century.
