(died 26 July 1886, aged 78), lumberman, described as a “lumber merchant” (1898), and as “one of the leading lumberman” of GC in “the early days” of the county (1911). He was married to Margaret McMartin (d. 27 Feb. 1877, aged 72). They were the parents of the lumbermen Alexander, Archibald, John, Peter McArthur, and of the physician R. D. MacArthur, and were grandparents of the lumberman John D. McArthur–all of them represented in this dictionary. He and his wife are buried in St. Andrew’s cemetery, Williamstown. He may have been the John McArthur who was proprietor of a general store at Martintown in 1857.
