Little is known of Roger Marston's beginnings, but he is estimated to have been born in England c.1235. He studied under John Peckham at Paris from 1269 to 1272. By 1276 he had returned to England and commented on the Sentences of Peter Lombard at Cambridge as the thirteenth Franciscan lector. In 1281 he became the sixteenth Franciscan regent master at Oxford. A decade later he was elected Franciscan provincial and held that office from 1292 to 1298. It is reported that he died in 1303 and is buried at Norwich. Of his writings, only his four Quodlibeta and his Quaestiones disputatae, dating from his Oxford regency, i.e. from 1281 to 1284, survive.
