Bradshaigh became a professed father in 1640 and rector of the English college at Liège in 1642. He was Provincial of the English province (1656–60) during the great political change in the collapse of the English Commonwealth and the restoration of the monarchy. He was rector of the English college at St. Omer from 1660 till his death on 12 February 1669.
Dodd ascribes to him a work on the Nullity of the Protestant Clergy in reply to Archbishop Bramhall, but the correctness of this statement has been questioned. Some interesting letters written by him in 1660 to Father General Nickell upon English affairs.
