Solomon Townsend was a merchant ship's captain prior to the American Revolution, owned an ironworks in New York State, and was a representative to the New York State Legislature. Stranded in London following the outbreak of hostilities, Townsend's passage back to America was facilitated by Benjamin Franklin. After the war he was a successful owner of an iron works plant, and a member of the New York State Legislature. One of his children followed him into the legislature and another was a founder of what became the New York Academy of Sciences.

Captain Robert Townsend was a Civil War-era ship captain in the United States Navy. He served twice, once before the war then again during the war. He saw active combat while serving aboard three ships, most notably as commander of the USS Essex from 1863 to 1864, an ironclad gunship on the Mississippi River. Captain Townsend died of heatstroke while commanding the USS Wachusett in China in 1866, and is buried in Albany, New York.
