Thomas Whittaker was a 17th-century English Roman Catholic priest born in Lancashire. After receiving his education in Valladolid, he returned to his home country to serve the local Catholic community. For several years, he ministered across various locations in Lancashire, including Claughton-on-Brock. His religious activities eventually led to his arrest, resulting in a long period of imprisonment. Despite facing significant pressure to renounce his faith to save his life, he remained steadfast in his convictions until his death.
