Edinburgh Academy register [1824-1914]

Scots around the world gather on the evening of 25 January to celebrate the birthday of Robert Burns, the author of many Scots poems, with a traditional Burn's Night Supper.
Like haggis his poetry is an acquired taste, although an adequate supply of Scotch helps make both more palatable.
A Scottish resource I've been saving for the occasion, from the Internet Archive, is the Edinburgh Academy register [1824-1914], a record of all those who entered the school from its foundation in 1824 to the start of the Great War. Search it for "Canada" and you'll find many alumni who settled or passed through during their careers, and three with an Ottawa connection.
