In Caribbean historiography, rumors are often associated with enslaved people and sailors; less often are they associated with elite men. This article addresses the use of rumor by elite men in the Lesser Antilles during the late 1820s, following the story of Antony O’Hannan, Roman Catholic rector of Grenada, whose relationship with his enslaved and free congregation made him dangerous to both Catholic and colonial authorities. Although the White Catholics of Grenada were often discriminated against, here they aligned with the wider Church in supporting the colonial power. Similarly, the colonial administration was willing to collaborate with Catholics, to activate an interisland rumor network that mobilized anxieties about O’Hannan’s perceived threat to White women. Using Colonial Office documents and Caribbean newspapers, this article explores microregional rumor as part of the arsenal used to maintain colonial order, and complicates the internal workings of the Catholic Church in the Caribbean.
