Following his suspension, Onderdonk remained Bishop of the Episcopal Diocese of New York but was suspended from performing his duties. Provisional Bishops were consecrated to fill his duties. They were Jonathan Mayhew Wainwright I, consecrated to serve as Provisional Bishop in place of Bishop Onderdonk, 1852–1854 and Horatio Potter consecrated in 1854 to serve as Provisional Bishop in place of Onderdonk; became diocesan in 1861. His brother, Henry Ustick Onderdonk, Bishop of Pennsylvania, was also suspended upon allegations of intemperance during the same time period.
