Analysis of information sources in references of the Wikipedia article "Sierra Leone Creole people" in English language version.
A substantial part of this ex-slave population was Yoruba, but members of ethnic groups from other regions of the Atlantic (Igbo, Efik, Fante, etc) were also very much in evidence in this coterie of Liberated Africans. Individuals from ethnic communities indigenous to Sierra Leone were significantly represented among the Liberated Africans [...] Many a Temne, Limba, Mende, and Loko resident of Freetown, influenced by local European officials and missionaries, would come in time to shed their indigenous names, and cultural values, to take on a Creole identity which gave them a better chance of success in the rarefied Victorian ambience[sic] of a progressively westernized Freetown society.
In neighboring Sierra Leone, the analogous group of liberated Africans delivered there by the British Navy are generally seen as having played a crucial role in the evolution of Krio.
