The Ottawa Hockey Club wore white Hockey sweaters from 1890 to 1896 with the embroidered crest of a Triskelion as the basic style.
A triskelion is also the symbol of the Isle of Man, Brittany, where the Stanley Family (Lord Stanley) ruled from 1405 to 1765.
It is likely the Triskelion was used to honor Lord Stanley and his family while they were in Ottawa, Ontario, as they were regulars at Hockey matches being played. Two of Lord Stanley's sons, Edward and Arthur played ice Hockey for the Rideau Rebels.
As Christianity came into the forefront in Ireland before the 5th century, AD, the triskele took on new meaning, as a symbol of the Trinity: Father, Son, and Holy Spirit, therefore, also a symbol of eternity.
Its popularity continues today as a decorative symbol of faith for Christians of Celtic descent around the world.
NOTE - The Triskelion crest shown above, is a close rendition of the original. They were hand embroidered at that time in history, so each Hockey sweater had a slightly different look.
