Francis Cheynell, an English clergyman, born in Oxford in 1608, died at Preston, Sussex, in 1665. He entered Oxford university in 1623, and at first took orders in the church of England, but in 1640 sided with the parliament, and in 1643 was made one of the assembly of divines. In 1646 he was one of the delegation to convert the university of Oxford to the parliamentary cause, and in 1648 took forcible possession of the Lady Margaret professorship of theology in that university, and also of the presidency of St. John's. But, unable to retain them, he retired to the living of Petworth, where he remained until the restoration. Cheynell had previously published a work entitled "The Rise, Growth, and Dangers of Soeinianism," in which he had violently accused Chilling worth, Archbishop Laud, and others, of Socinian tendencies. After the death of Chillingworth he published a book entitled " Chillingworthi Novissima; or Sickness. Heresy, Death, and Burial of William Chillingworth" (1644).
