He next accepted a post as assistant master at his old school at Winchester under Thomas Hyde. But soon after the accession of Elizabeth I of England, both of them found it necessary to quit the country. Marshall retired to Leuven, where a number of English Catholic exiles were residing.
Thence he removed to Douai, when he joined the new university recently founded there, and graduated Bachelor of Divinity in 1567.
Thus it came about that when Allen arrived to found his new college, Marshall was already in residence, and attached himself to the new foundation. He did not, however, remain long, chiefly because of the smallness of the allowance which it was possible to give.
Later on, he obtained a canonry in the church of Saint Peter at the neighbouring city of Lille. Owing to the disturbed state of the country, he was not installed until 1579.
He lived to enjoy his dignity for eighteen years.
