John Mills Jackson

1764 - 1836


Son of Josias Jackson MD (q.v.). He has an entry in the Canadian Dictionary of Biography as 'author, merchant and JP' which gives his father as Josiah and says of him: 'After receiving a BA from Balliol College, Oxford, in 1783, John Mills Jackson resided on St Vincent, where he owned property. He claimed to have lost a “considerable” portion of it during the Carib uprising of 1795. Four years later he became aide-de-camp to the island’s commander-in-chief. At some point thereafter he returned to England (possibly to Wiltshire), but he left in 1805 to visit Lower Canada. There he possessed, “by right of inheritance, a claim to a large and very valuable tract of land.” He also had an interest in Upper Canada and, prior to leaving England, he purchased land there.'
