Mongon Warburton Clan
Ray Warburton
In 1792 Charles Mongan, the future Bishop of Cloyne, changed his name to Warburton, the name of his maternal cousins.  His descendants form  a second clan of Irish Warburtons, though it is not yet known if Charles’s cousins are of the Garryhinch clan.

The image is of the Bishop’s Palace where I believe Charles Mongon Warburton died in 1826.
