Question: What country did McGillivray return to before taking a trip to Scotland and England? Passage:McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.

Question: At what age did the first Spanish governor of Las Californias when die? Passage:During the expedition, Father Crespi observed a location along the river that would be good for a settlement or mission. However, in 1771, Father Serra instead commissioned two missionaries to establish the Mission San Gabriel Arcangel-San Gabriel Mission near the present day Whittier Narrows section of the San Gabriel River. The missionaries encountered resistance from the Tongva to their attempts to resettle the Natives on the mission. The mission encountered further trouble in 1776 when a flood damaged the mission, convincing the missionaries to move and rebuild the mission on a higher and more defensible location: its present site in San Gabriel. The first Spanish governor of Las Californias, Felipe de Neve had, as well, recommended to Viceroy Bucareli Father Crespi's location on the Rio Porciuncula (Los Angeles River) for a mission. Instead, in 1781, King Charles III mandated that a pueblo be built on the site instead, which would be the second town in Alta California, after San Jose de Guadalupe in 1777. The monarch, disregarding the production and trade roles of the missions, saw a greater need for secular pueblos to be established as the centers of agriculture and commerce to supply the crown's ever-growing military presence in "Nueva California." The priests at the missions ignored the royal mandate and continued their ranching, trading and production of tallow, soap, hides, and beef, often in competition with new pueblo ventures.
