[5][6] His father was a tenant of the Seigneur of Argenteuil James Murray, and died when he was young, drowning in North River, Newfoundland.

This post had just been built by John Clarke in an effort to secure a foothold for the HBC in Athabasca, the great stronghold of the North West Company.

"[10] - The entry in Fort Langley: Outpost of Empire, by Chief Whattlekainuma, a sub-chief of the Kwantlen First Nation (Halkomelem: qʼʷa:n̓ƛʼən̓), referring to the fur traders as Sky-peopleIn 1826, he is recorded as a correspondent of fur trader John Stuart, uncle of Lord Strathcona & Mount Royal of Knebworth House.

[13] Yale then replaced Deputy Governor Archibald McDonald, husband of Princess Raven, the daughter of King Comcomly, a native Indian, as Chief trader on February 20, 1833.

[14] He achieved great success at Fort Langley, dealing in furs and pelts with the Indians, manufacturing wood barrels, and exporting cured salmons, which commanded high prices during the Crimean War of Napoleon III.

[15] During his tenure, Yale would be saved by his postmaster from another murder attempt on his life, this time, by Tzouhalem, the chief of the Cowichan tribes.

[17] While Yale was building his new fort, Sir George Simpson was at Hamburg, Germany, discussing with Baron Ferdinand von Wrangel, Governor of Russian America and Minister of the Navy.

The Baron was the representative of the Russian-American Company, a fur trading enterprise chartered by Tsar Paul I of Russia, son of Catherine the Great.

The salmon trade would eventually become a world-trade industry for the Fort and the area, developed by him and chief trader Archibald McDonald.

Eventually, the fur returns were on the decline and the shareholders in London were alerted, as a new technology made its apparition, the steamer Beaver.

Yale also developed during his tenure much of the largest farms of what is now called British Columbia, exporting products as far as Hawaii and Alaska.

[23] With unwelcomed foreigners and speculators coming in for the gold rush, the relationships established with the Indians and the supply chains were seriously disturbed.

With the prospect of wealth, the population of the United States territory of Washington and Oregon, as well as Europeans and other Indians tribes, were excited and came by all means of travel.

Many administrative positions were created to better handle the gold rush and the monopoly agreement with the Hudson's Bay Company was revoked.

[28] Having worked so hard at building the trading operations at Fort Langley for the last 30 years, and seeing the HBC being displaced by the British, Yale decided he had enough and took his retirement.

[29] In its heyday, the fort consisted of assistant traders, blacksmiths, boat builders, baril makers, carpenters, coopers, interpreters, laborers, and middlemen.

[30] Yale married a local Princess (Halkomelem: qʼʷa:n̓ƛʼən̓) named Quaitlin, daughter of the Chief of Kwantlen Nation.

[48][49][50] Andrew's son was Postmaster, and number of his grandchildren lived in Outremont, Montreal, with one cofounding a Quebec mining company with $150,000 in capital.

[57][58] Notable shareholders in the charter of 1900 included Senator Sir Alexandre Lacoste, Outremont founder Louis Beaubien, Judge Louis-Philippe Pelletier, Governors Narcisse Pérodeau and Louis-Amable Jetté, and Montreal Mayors and Senators Sir William H. Hingston, Charles Wilson and Alphonse Desjardins.

Chief Factor Sir James Douglas, Governor of the Colony of British Columbia, his superior in the HBC, a big man, took a quiet delight in standing near Yale and observing his discomfiture.

In his famous “Character Book”, Governor Simpson devoted an entry to Yale: “A sharp active well conducted very little man but full of fire with the courage of a Lion.

Deficient in Education, but has a good deal of address & Management with Indians and notwithstanding his diminutive size is more feared and respected than some of our 6 feet men.”[3]“--The entry in the Dictionary of Canadian Biography, Volume X
