One of the Brooklyn's passengers in later years became a leader in the settlement of Mesa, Arizona. He was Geo. W. Sirrine, a millwright, whose history has been preserved by a son, Warren L. Sirrine of Mesa. The elder Sirrine was married on the ship, of which and its voyage he left many interesting tales, one being of a drift to the southward on beating around Cape Horn, till icebergs loomed and the men had to be detailed to the task of beating the rigging with clubs to rid it of ice. When danger threatened there was resort to prayer, but work soon followed as the passengers bore a hand with the crew. Sirrine, who had had police experience in the East, was of large assistance to Brannan in San Francisco, where the rougher element for a time seized control, taking property at will and shooting down all who might disagree with their sway. It was he who arrested Jack Powers, leader of the outlaws, in a meeting that was being addressed by Brannan, and who helped in the provision of evidence under which the naval authorities eliminated over fifty of the desperados, some of them shipping on the war vessels in port. Some of the Mormons still had a part of their passage money unpaid and these promptly proceeded to find employment to satisfy their debt. The pilgrims' loyalty appears to have been of the highest. They had purchased arms in Honolulu and had had some drill on the passage thence. At least on one occasion, they rallied in San Francisco when alarm sounded that hostile Mexicans might attack. According to Eldridge, historian of San Francisco: "The landing of the Mormons more than doubled the population of Yerba Buena. They camped for a time on the beach and the vacant lots, then some went to the Marin forests to work as lumbermen, some were housed in the old Mission buildings and others in Richardson's Casa Grande (big house) on Dupont Street. They were honest and industrious people and all sought work wherever they could find it." Brannan's Hope of Pacific Empire A party of twenty pioneers was sent over to the San Joaquin Valley, to found the settlement of New Hope, or Stanislaus City, on the lower Stanislaus River, but the greater number for a while remained on the bay, making San Francisco, according to Bancroft, "for a time very largely a Mormon town. All bear witness to the orderly and moral conduct of the Saints, both on land and sea. They were honest and industrious citizens, even if clannish and peculiar." There was some complaint against Brannan, charged with working the Church membership for his own personal benefit.
