McGowan anglicises the Gaelic Mac an Ghabhann, "son of the smith," honouring a craft that held a place of real respect in Gaelic Ireland — in County Cavan the name was sometimes translated directly into English as Smith. The name is associated particularly with Connacht and with Cavan and the north, where Mac an Ghabhann families were long established.
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 McGowan collection currently includes ceramic ornament, mug, woven blanket, T-shirt, novelty license plate, coaster set, and garden flag. The woven blanket is the most substantial home piece where available. Designs use the McGowan name and crest; where Irish National Tartan appears, it is a shared Irish heritage background rather than a hereditary family tartan.
