1) Information on this specific subject is currently unavailable to the IRBDC in Ottawa. However, according the The New Encyclopedia Britannica (1989, 846), the Dagomba are a patrilineal society although matrilineal descent is also recognized reportedly for its "contribution to spiritual attributes" (Ibid.). This source adds that
For the chiefly class, the important kinship unit is a descent group known as the dang, composed of all descendants of a single grandfather or great-grandfather through both male and female lines. In the centralized Dagomba state, only the sons of a previous paramount chief, the ya-na, may rise to that office, which is filled in rotation by one of the three divisional chiefs.

2) Information on the death of the king/chief of the Dagomba in the northern region and on his successor is currently unavailable to the IRBDC in Ottawa.
