Dictionary of National Biography, 1885-1900/Maurice, William
MAURICE, WILLIAM (fl. 1640–1680), Welsh antiquary, was a gentleman of good family and landed property, and lived at Cevnybraich, in the parish of Llansilin, Denbighshire, where he built a library in which he spent most of his time studying Welsh literature. He was an industrious collector and transcriber of Welsh manuscripts, and his collection is preserved at Wynnstay; a chronological account of the civil war in North Wales from his notebook was published in the ‘Archæologia Cambrensis,’ i. 33-41. He died between 1680 and 1690.
