The _Tref_ thus, in the main, corresponds to the _Ballyboe_ or ploughgate of the Irish system, and the fifty _Trefs_ of the _Cymwd_ were thus distributed among the people. Sixteen _Trefs_ formed the _Tir Cyfrif_ or register land, occupied by the _Bonedic_ or free members of the tribe. Eight _Trefs_, or two _Maenawls_, were assigned to the _Cynghellawr_ and the _Maer_ who represented the king in the Cymwd, and divided the register land among the people. Twenty-four _Trefs_, or six _Maenawls_, were the _Tir Gwelyawg_ or inheritance land, possessed by the free _Uchelwyr_; and the two _Trefs_ which remained over were the king’s _Tir Bwrdd_ or mensal land. Under the _Uchelwyr_ there was a similar distribution of land, and it is obvious that what was originally the common land of the tribe, had now come to be viewed as the property of the king; and the _Bonedic_, or original free occupiers of the land, now appear as the king’s _Aillts_. Though, like the Irish _Ceile_, they came to occupy a dependent position in relation to the superior, their original mode of occupation of the soil remained unchanged, and the _Maer_ and _Cynghellawr_ are directed to share this land equally between all in the _Tref_ or township, and on that account it is called _Tir Cyfrif_ or register land. On the other hand, the sons succeeded equally to the _Tir Gwelyawg_ or inheritance land, and if they failed, it went to their first and second cousins, after whom there was no further division, a succession very similar to the Irish Gavelcine.
