A common tale states that Tilley was the originator of the word "Dominion" in Canada's name. The Fathers of Confederation had been discussing what to prefix Canada with, Kingdom of Canada being Macdonald's preference. During morning devotions, in St Andrew's in the backyard of his cousin, Dr Samuel Tilley GOVE, (the editor's great-great-grandfather, who also has the Psalter used by Tilley), before the two of them headed down the street to Church, Tilley read Psalm 72:8, which states "He shall have dominion also from sea to sea, and from the river unto the ends of the earth", and presented this inspiration to the others, being as their ambition was to stretch the new nation to the Pacific Ocean and from the St Lawrence River to the North Pole. "Dominion" had been used before, but Tilley pushed hard for it to be adopted in reference to Canada, despite Macdonald's preference.
