He sailed back to England, served in the British Navy, fought in the Crimean War and was awarded the Crimean Medal of Valor.
By 1857, he was in Colorado prospecting for gold at Pike’s Peak. In 1859, he traveled to Louisville, Kentucky where he married Mary Ann Chapman Lambert, who had a daughter, Mary Ann Lambert, who was later adopted by John O’Farrell.

From 1871-1878, John O’Farrell and his family lived in the Salt Lake City area where he mined at Park City, Utah. While in Utah, they suffered the loss of three children.
The O’Farrell family donated a clock of land for the first Catholic Church in Boise, St. Patrick’s. He was one of the original investors of the New York Canal and was also politically active, serving a term in the Territorial Legislature.
