_Roger Williams_ was a native of Wales, where he was born in the year 1599. He was entered for the church, and was accordingly educated for it; but adopting puritanical principles, he emigrated to North America, where he founded the town of Providence. He distinguished himself by his zeal for the conversion of the Indians to Christianity, of whose language he published a very useful “Manual and Glossary,” which has been frequently reprinted. His colony thrived rapidly, as he was decidedly opposed to all restraint in religion, and granted to all who settled there free liberty of conscience. He died in 1683. _Thomas Williams_ was a native of Caernarvonshire, and received an University education at Oxford. He practised as a physician at Trevriw, near Llanrwst, and he wrote a “Welsh and Latin,” and “Latin and Welsh Dictionary,” which he left in manuscript; and it was subsequently published in 1632, with many additions and corrections by Dr. John Davies. He made a good collection of pedigrees, which he entitled “Priv achau holl Gymru Benbaladr,” i.e. The Primitive Pedigrees of all Wales. In 1606 he was proceeded against as a Papist in the court of Bangor, and in the following year he was excommunicated. There was written also by him a large “List of Plants” in Latin, Welsh, and English. _William Williams_ was a native of the Isle of Anglesea. He was educated at Oxford, and in 1652 he was elected scholar of Jesus’ College, whence he removed to Gray’s Inn. In 1667 he was appointed recorder of the city of Chester. When the Popish plot broke out, he sided with the party then dominant; and in 1678 he was chosen one of the representatives of the City of Chester, and again for the parliament which sat in 1679, and a third time in 1680; in the two last parliaments he was chosen speaker of the House of Commons. After the Presbyterian plot broke out in 1683, he became an advocate for them and the fanatics. When James the Second came to the crown, he was taken into favour, and was made solicitor-general instead of Sir Thomas Powis, who was appointed attorney-general in 1687. Williams was knighted on this occasion, and soon afterwards created a baronet. He has published several of his eloquent speeches, besides some other works.
