 During the latter period he was assisted by a bishop of Maenan, the only instance of a place-name being given for this purpose subsequent to Disestablishment.Cultured but with a reputation for authoritarianism, a representative of the High Church tradition, Green wrote a work on the church dedications of the Llandaff and Monmouth dioceses and the definitive guide to the constitution of the Church in Wales.He died at Bishopcourt, Bangor, aged 79.
