"When [William Douglas] sailed to Parry Passage in 1788 on the Iphegenia, the lateness of the season prevented more than a brief visit. When he returned to trade in June of the following year his mission was accomplished at the beginning of a spell of superb weather. Douglas taking advantage of this became probably the Charlottes' first tourist - nosing into every bay and cove along the channel now known as Parry Passage. It was he who left the name of Cox for this region - applying it to the passage after John Henry Cox, one of the owners of the Ipheginia. Later this name was deleted and reapplied to an island in Cloak Bay." and "...the snow Iphigenia Nubiana [was] owned by the Associated Merchants Trading to the Northwest Coast of America, who were John Meares, John H. Cox, Richard C. Etches, John W. Etches, William Fitzhugh, Henry Land and Daniel Beale." See also Cox Island (102I/15).
