The territory of this great sept lay on the southern shores of Lough Neagh, and the MacCanas were lords of Clanbrassil, a district in County Armagh originally occupied by the O'Garveys. Several members of the sept are described in the "Annals of the Four Masters"; the last to be mentioned in the Annals was killed in 1260. Donnell MacCanna, Chief of Clanbrassil, was recorded in 1598, and the surname is still widespread in the vicinity of Lough Neagh, though uncommon elsewhere.

A Coat of Arms granted to the M(a)cCann family is an azure shield with gold fretty, on a silver fess a red boar passant, the Crest being a salmon naiant proper.

Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
