A system much used overseas, primarily in South Africa, is the de Villiers/Pama system. The following information regarding the system was written by Steve Hayes of South Africa amd sent to the authori in 1991.
The de Villiers/Pama system was invented by Chris. de Villiers, who used it in his published work Genealogies of Old Cape Families. published in the 1890s, I think, and revised more recently by Dr. Cor Pama. The same numbering system is now being used in a new work called Genealogies of South African Families, by Heese & Lombard, published by the Human Sciences Research Council.
The original ancestor you start numbering from is a. Every subsequent generation takes the following generation letter, so the children of a are b, the grand children c, and so on. Each child is given a number - the oldest is 1, the second 2, and so on.
So the children of a are
b1 b2 b3Their children are
b1 c1 c2 d1 c3 d1 d2 b2 c1 c2and so on. Thus the third child of the second child is b2.c3
