Brother Jonathan was a paddle steamer that struck an uncharted rock near Point St. George, off the coast of Crescent City, California, on July 30, 1865. The ship was carrying 244 passengers and crew, with a large shipment of gold. Only 19 people survived, making it the deadliest shipwreck up to that time on the Pacific Coast of the United States. Based on the passenger and crew list, 225 people are believed to have died. Its location was not discovered until 1993 and a portion of the gold was recovered in 1996.
On its last voyage, the ship had been heavily loaded and according to DeWolf's widow, he felt that the ship sat too low in the water, even without the passengers, but he was told that if he did not set sail, he would be fired and replaced by someone else. When it came time to depart, the bottom of the ship had sunk into the mud and they had to wait until high tide for a tugboat to pull her out.
