"In 1786, when only 26 years of age, [Captain Charles William Barkley] left the service of the East India Company to take command of the Loudon, alias the Imperial Eagle, which was being outfitted in the Thames River for a trading voyage to the Pacific Northwest coast. While in Ostend, Barkley met and married Frances Hornby Trevor, the 17 year old daughter of the Protestant minister. The marriage took place 27 October 1786. When the Imperial Eagle sailed four weeks later, Mrs. Barkley courageously accompanied her husband on the voyage ... Her unpublished reminiscences, written in the latter days of her life, and now in the Provincial Archives in Victoria, are the main source of information about this and later voyages.... In her reminiscences Mrs Barkley wrote, ' this part of the coast proved a rich harvest of furs. Likewise another very large sound to which Captain Barkley gave his own name, calling it Barkley's Sound. Also several coves, bays and islands in the sound we named. There was Frances Island, named after myself; Hornby Peak, also after myself; Cape Beale, after our purser; Williams Point and a variety of other names'...."

Mrs. Barkley kept an interesting journal of the voyage, and from this book the incidents narrated here are taken.... ...Mrs. Barkley died in 1843."
