The Allan Shipping Line was started in 1819, by Captain Alexander Allan of Saltcoats, Ayrshire, trading and transporting between Scotland and Montreal, a route which quickly became synonymous with the Allan Line. By the 1830s the company had offices in Glasgow, Liverpool and Montreal. All five of Captain Allan's sons were actively involved with the business, but it was his second son, Sir Hugh Allan, who spearheaded the second generation.
