Calvert, James an English nonconformist divine, was born in York and educated at Clare Hall, Cambridge. He had been for several years at Topcliffe when he was silenced by the act of uniformity; after which he retired to York, and lived privately, but studied diligently. As a result of his studies here, he brought out his work, entitled Naphthali, seu Collectatio Theologica, de Reditu Decem Tribuum, Conversione, et mMensibus Ezekielis (1672). About 1675 he became chaplain to Sir William Strickland, and, afterwards, to Sir William Middleton and tutor to his son. He died in December, 1698. See Chalmers, Biog.
