Thomas Notley (Cerne Abbas, Dorset, England 1632 - 3 April 1679) was the 8th Proprietary Governor of Maryland from 1676 through 1679. Having first moved to Barbados he immigrated to America in 1662. He was the speaker of the legislature in 1666. He and fellow Barbadian immigrant Jesse Wharton passed slave codes similar to those in Barbados that punished those who helped in the escape of a slave or who stole and kept another planter’s slave for themselves.
