Titus Hosmer (1736 – August 4, 1780) was an American lawyer from Middletown, Connecticut. He was a delegate for Connecticut to the Continental Congress in 1778, where he signed the Articles of Confederation.
Hosmer was elected to the Connecticut State Assembly annually from 1773 to 1778, and served as their speaker in 1777. In May 1778 he became a member of the State Senate, and remained in that office until he died. Later in 1778, the joint state legislature also sent him as one of their delegates to the Continental Congress. He was subsequently elected by the Continental Congress on January 22, 1780 to serve as a federal judge on the Court of Appeals in Cases of Capture.
Titus died at Middletown on August 4, 1780 of undisclosed causes, and is buried in the Mortimer Cemetery there. Joel Barlow, who received Titus's patronage, wrote a much-admired elegy on Titus's death.
Titus Hosmer married Lydia Lord on November 29, 1761, in Middletown. One son, Stephen Hosmer, would also become a lawyer, and was the Chief Justice of the Connecticut Supreme Court. The other son, Hezekiah Lord Hosmer (1765–1814), became a U. S. representative for New York State. A grandson, also named Hezekiah Lord Hosmer (1814–1893), became the first Chief Justice of the Montana Territory and authored several books.
The Hosmer family is traced to Rotherfield in Sussex (and much earlier to Otterhampton, Somerset), where a certain Alexander Hosmer was native before a marian martyr in nearby Lewes and the family consequently moved to Kent in the following generations. His colonial ancestor, Col. Thomas Titus, was a Roundhead in the New Model Army, who left Hawkhurst in Kent for Boston upon the English Restoration. Thomas Titus later settled in Middletown.
He had a Whig relative who fought and was mortally wounded in the Battle of Lexington and Concord against Hugh Percy, 2nd Duke of Northumberland. There is a Hosmer Corner in Hampden County, Massachusetts named for the family although the Hosmers are more renowned as founders of Hartford Connecticut.
