Henry Augustus Osborn [was] a pioneer of 1850 in California. He was born in Oxford, Conn., on February 13, 1829, grew up there until he was sixteen, then came to California via Cape Horn. Much suffering was endured by the passengers on that eventful journey, but finally young Osborn arrived in San Francisco, where he later engaged in the draying business. He was a member of the San Francisco Vigilant Committee of that early day and was always much concerned in the world events during his entire lifetime. He was a step-brother of the late J. W. Mitchell, a Forty-niner and a San Joaquin Valley pioneer. Mr. Osborn peddled goods out of San Francisco and Stockton to the miners in Tuolumne and Amador Counties in a cart drawn by oxen; and he also mined in that section. He went through the flood of 1862 while he was ranching on the Mitchell place on Cherokee Lane between Stockton and Wood­bridge. He farmed on a large scale for that period as the harvesting was done by hand; no modern conveniences were even thought of at that time. He went to Jackson, Amador County, and for seven years mined in what was once the richest of the gold fields at Poker Flat; he also got out timbers for the mines and did some farming on 160 acres. In 1868 Mr. Osborn went to Turlock and for a time rented land of J. W. Mitchell, but later he invested in 640 acres one mile west of town, the property adjoining the cemetery. Today that same ranch is under irrigation and divided into ten and twenty-acre farms. He married on May 13, 1855, Minerva Jane Baker, born in Arkansas, but living in Amador County. She crossed the plains with an ox-team with her parents, Mr. and Mrs. William Baker, who settled at Poker Flat. William Henry Osborn was the eldest of six (four living) children [William, John Benton, Ellen A, Edward Benjamin and Mary]. She died at the age of forty-nine, survived by five children. Mr. Osborn died on January 4, 1915, aged eighty-six.
