Some Corrections 

 Props to Shiraz4 for the organizing of the Kongo kings into houses. However, there are errors in the assignment which I have sought to correct.  In the seventeenth century, it's clear that the acession of Alvaro I marks the advent of the house of Kwilu, and the other houses are also well documented.  For the later 18th and 19th century we need to do more research before we can assign house membership, as, although sources of the time refer to two or three houses, they don't always name them (this would be the Castello de Vide and Raimondo da Dicomano reports).  Hints about this are found in traditions, as recorded in Nkutama a mvila za makanda, and Kinkulu kia Nsi Eto, and their names might still be recoverable.  However, to do this would be to provide original research and until that is published it seems premature to put it in Wikipedia.  I asked about these matters when I did field research at Mbanza Kongo in 2002 but no one seems to know about this these days.
