The Catholic faith infiltrated Northern Uganda through the work of the Verona Fathers now known as Comboni Missionaries; Bishop Daniel Comboni who became the Apostolic Vicar of Khartoum in the Vicariate of Central Africa (in December 1877) founded this Congregation. After his death in 1881, the Comboni missionaries continued with the work under Bishop Xavier Francis Geyer moving southwards from Bahrel Ghazal through Gondokoro where they reached on 18th of January 1910, then Nimule until they arrived in Pakwach. At Nimule on the Uganda-Sudan boarder, they were not allowed to enter Uganda as they could not produce an entry permit except a recommendation from the Governor General of Sudan. But later, they were cleared from Entebbe and at last on 17th of February 1910, they reached their destination; the government post of Koba, a settlement on the Eastern bank of River Nile more or less facing the Present day Pakwach.
