Of what members of the _Finé_, then, did each of these groups really consist? There seems to be no doubt as to the number which formed the members of each. The _Geilfiné_ consisted of five persons only, who were nearest of kin to the chief, but these might be found either in the descending or ascending line, or were, in the strictest sense of the term, collateral. The descending line was termed _Belfiné_, and the _Geilfiné_ consisted of the father, the son, the grandson, the great-grandson, and the great-great-grandson, to the fifth generation. The ascending line was termed _Culfiné_, or back family, and we are told that, viewed in this connection, the _Geilfiné_ consisted of the father’s brother, and his son, to the fifth generation.[202] The collateral relationship was termed _Taobhfiné_, or side family; and, according to Mr. O’Donovan and the authorities he refers to, the _Geilfiné_ is defined as ‘the first or direct family; the father and his two sons, and two grandsons; collateral tribe.’ The _Deirbhfiné_ as ‘the second tribe; the next in point of dignity to the _Geilfiné_; the two grandsons and their two sons.’ The _Iarfiné_ as ‘the after family; two sons of grandsons and their sons, making four persons;’ and _Indfiné_ as ‘the fourth and lowest division of a tribe.’[203] He does not define the members of which it consists, but it may be inferred that he held it to consist of the two sons of great-grandsons and their sons, corresponding to the five generations of the Brehon Laws.
