Parsons died on 21 June 1741 at his home in Molesworth Street Dublin in the parish of St Anne. On his deathbed he received a letter from the vicar of St Anne, the dean of Kilmore “to remind him of his past life, the particulars of which he mentioned, such as profligacy, gaming, drinking, rioting, turning day into night, blaspheming his Maker, and, in short, all manner of wickedness; and exhorting him in the tenderest manner to employ the few moments that remained to him, in penitently confessing his manifold transgressions, and soliciting his pardon from an offended Deity, before whom he was shortly to appear.”
