(fl. 1820s), mill owner. William Roebuck was given a grant in 1829 by the Court of Quarter Sessions to open a road through the 8th and 9th Concession of Lancaster Township to his mill at what is now Dalhousie Mills. The name of the mill site was known for a time as Roebuck’s Mills. The Cornwall Observer of 24 June 1841 had the announcement, “Valuable Mill Property for Sale in the County of Glengary. The Executors to the Estate of the late Mr. John Millar, offer for Sale, the Valuable Grist and Saw Mills, with all the Buildings and Water privileges, as occupied by him in his lifetime. They are situated on the River Delisle, and are known as Dalhousie Mills, their former designation being Roebuck’s Mills.” (issue 18 Nov. 1841 also, and Montreal Gazette 23 June 1841) A Gaelic form of the place name has been written as “Mullan Roebuck’s.” It has been suggested that Roebuck had a family connection with the Roebucks of the Sears-Roebuck Company.
