He was born at or near Ripon and arrived at the English College, Reims, 17 April, 1589. He received the first tonsure and minor orders 18 August, 1590, the subdiaconate at Laon on 22 September, and the diaconate and priesthood at Soissons on 30 and 31 March, 1591.
He left for England on the following 15 May. He was arrested about 1 May, 1598, when on his way to York with Ralph Grimston of Nidd. Both were shortly after condemned by representatives of a virulently anti-Catholic government (headed by Elizabeth I). Fr. Snow was convicted of treason because he was a Catholic priest and Grimston of felony, for having aided and assisted Snow, a Catholic priest.
