It was said that Bishop Markham’s “crowning achievement was that a Bahamian succeeded him in the See of Nassau and The Bahamas”. The first Bahamian Bishop (and eleventh Bishop) of Nassau and The Bahamas was the Right Reverend Michael Hartley Eldon. Bishop Eldon and his mother, Mrs. Rowena Eldon lived in the House until 1990. The Reverend John Taylor has written of Bishop Eldon,
Anyone acquainted with Bahamian history knows of the flowering of Bahamian-born Anglican clergy during Bishop Eldon’s Episcopate. The Holy Spirit used his intellectual gifts, energy and charisma, to inspire vocations to the Sacred Ministry as never before in the Diocese. From one parish after another, he sent men to Codrington College, Barbados, and other theological seminaries. [Booklet in honour of Bishop Eldon’s 70th Birthday, p.201]
The tradition of hospitality at Addington House continued under Bishop Eldon and guests during this time included previous Archbishops of the Province of the West Indies, the Most Reverend Alan Knight and the Most Reverend Cuthbert Woodruff. However, by 1990, it was found that there were serious structural problems developing, which made it unsuitable as a residence and Bishop Eldon moved to other accommodations.
