Teffia and Ferrard, two of his nephews, and others of his personal attendants and companions. The Dublin Danes had in their turn a day of rejoicing and of revenge for the defeats they had suffered at Congal's hands. This reign is not only notable for the imputed first conversion of the Danes to Christianity, but also for the general adoption of family names. Hitherto, we have been enabled to distinguish clansmen only by tribe-names formed by prefixing _Hy_, _Kinnel_, _Sil_, _Muintir_, _Dal_, or some synonymous term, meaning race, kindred, sept, district, or part, to the proper name of a remote common ancestor, as Hy-Nial, Kinnel-Connel, Sil-Murray, Muintir-Eolais, Dal-g Cais, and Dal-Riada. But the great tribes now begin to break into families, and we are hereafter to know particular houses, by distinct hereditary surnames, as O'Neill, O'Conor, MacMurrough, and McCarthy. Yet, the whole body of relatives are often spoken of by the old tribal title, which, unless exceptions are named, is supposed to embrace all the descendants of the old connection to whom it was once common. At first this alternate use of tribe and family names may confuse the reader—for it _is_ rather puzzling to find a MacLoughlin with the same paternal ancestor as an O'Neill, and a McMahon of Thomond as an O'Brien, but the difficulty disappears with use and familiarity, and though the number and variety of newly-coined names cannot be at once committed to memory, the story itself gains in distinctness by the change.
