The purpose of this research, presented at the Conference sectional meeting, is to tracepeculiarities of transformation of British folk medieval ballads, which were brought to theSouthern Appalachians in the east of the USA by British immigrants at the end of the XVIIIth –beginning of the XIXth century and retained by their descendants, through analyzing certain textson the levels of motifs, dramatis personae, composition, style and artistic means, as well as tooutline relevant Ukrainian parallels. The analysis of such ballads, plot types and epic songs wascarried out: 1) British № 10: “The Twa Sisters” (21 variants); American “The Two Sisters”(5variants) and Ukrainian plot type I – C-5: “the elder sister drowns the younger one because of envyand jealousy” (8 variants); 2) British № 26: The Three Ravens” (2), “The Twa Corbies” (2);American “The Three Ravens” (1), “The Two Crows”(1) and Ukrainian epic songs with the motif oflonely death of a Cossack warrior on the steppe (4). In our study British traditional ballads areclassified according to the grouping worked out by the American scholar Francis Child(305 numbers), Ukrainian folk ballads – the plot-thematic catalogue developed by the Ukrainianfolklorist Оleksiy Dey (here 288 plots are divided into 3 spheres, cycles and plot types). Theinvestigation and comparison of the above indicated texts witness such main tendencies: 1) theAmerican counterparts, collected in the Appalachian Mountains, preserve the historic-nationalmemory and cultural heritage of the British immigrant bearers on the level of leading motifs,dramatis personae, composition peculiarities, traditional medieval images, epithets, similes,commonplaces; 2) some motifs, characters, images, artistic means, archaic and dialectal English ofthe Child ballads are reduced or substituted in the Appalachian texts; 3) realism of Americanballad transformations, which overshadows fantasy and aristocracy of their British prototypes, issimilar to the manner of poetic presentation of the typologically-arisen and described events by theUkrainian folk ballads and dumas .
