Rev. Samuel Clark, Jr. (1727-69), was a student of Philip Doddridge at Northampton (class of 1745) and assumed Doddridge's duties as minister at Castle Hill and principal of the academy upon Doddridge's illness and departure from Northampton in 1751. However, he was replaced after Doddridge's death as Principal of the Academy by Caleb Ashworth of Daventry, who promptly transferred the Academy there. Clark moved to Daventry as well and served as a tutor for Ashworth until 1757, when he became co-pastor of the Old Meeting at Birmingham. He also served as minister at the Presbyterian meeting in Oldbury, maintaining both duties until his death in 1769. He subscribed to Volume 4 of Doddridge's Family Expositor in 1753. His daughter, Sarah, married Dr. William Rose, a schoolmaster at Chiswick and former student of Doddridge. His daughter, Ann (1733-1804), married the Rev. Jabez Hirons, who succeeded Samuel Clark, Jr., as minister at the Dagnall Lane congregation in St. Albans. Jabez and his cousin, Thomas Hirons (d. 1774), were both students of Doddridge at Northampton in the class of 1745 and were subscribers to Volume 4 of Doddridge's Family Expositor in 1753. Clark's other daughter, Elizabeth, married the London printer/bookseller Ralph Griffiths, proprietor of the Monthly Review, in 1767.
