His other achievements included gaining collegiate status for St. Nicholas's church, thus making the town ecclesiastically independent.
He funded the construction of what would become the church's south aisle and the building of a college house for the clergy.
His known children were John, Stephen, Gabriel, Peter, Kathleen, Anastasia and Agnes.
His will detailed his properties, bequests, merchandise, as well as large sums of silver and gold.
