Fergus references the popular Scottish clan name Ferguson whose Gaelic meaning is angry, audacious, and proud. The Ferguson clan is known for helping to popularise tartan. Amongst Celtic peoples, Tartan is a typical motif, and it is described as a wool based material with a pattern of criss-crossed horizontal and vertical lines in a range of colours. Tartans were originally seen only on fabric but are now used on many other materials. Scottish kilts are almost always made in a tartan-patterned fabric.
