McNeill anglicises the Gaelic Mac Niall, "son of Niall" — a name of extraordinary prestige in Irish tradition, borne by Niall of the Nine Hostages, the legendary founding ancestor of the Uí Néill dynasty. The family is native to County Antrim and County Down, concentrated especially in the Glens of Antrim, a coastal territory that looked across the North Channel to Kintyre and produced a long history of exchange with the closely related Scottish MacNeills.
The Gaelic form and regional setting are the useful starting points for research, since a modern surname can represent more than one historic line.
The McNeill collection currently includes mug, woven blanket, novelty license plate, coaster set, garden flag, and ceramic ornament. The woven blanket is the most substantial home piece where available. Designs use the McNeill name and crest; where Irish National Tartan appears, it is a shared Irish heritage background rather than a hereditary family tartan.
