Augustus Alexander Warren was a warrant officer with the United States Navy in the mid-1800s. He was born to a French mother and an English father in Havre, France, in February of either 1826 or 1827. When a young man, Warren emigrated to Kittery, Maine, where he became a U.S. citizen in 1853 and received his commission as a sail-maker with the Navy the same year. Soon after, he set to sea on the USS Decatur to defend Seattle against "all the Indians occupying the Northern portion of the United States." Warren also sailed in support of the Charles Francis Hall Arctic expedition in 1871 and along the coast of South America in the 1880s.
