David Colbreth Broderick was a Democratic U.S. Senator from California. He was a first cousin of Andrew Kennedy and Case Broderick.
Broderick was born on East Capitol Street just west of 3rd Street in Washington, D.C., the son of an Irish stonecutter who had immigrated to the United States in order to work on the United States Capitol. Broderick moved with his parents to New York City in 1823, where he attended public schools, and was apprenticed to a stonecutter.
