I believe it is a d'Aboville number.

The d'Aboville numbering system is a way of numbering descendants of a person.
The starting person is given the number 1. His first child is numbered 1.1, his second child is 1.2, his third child is 1.3, etc. The children of 1.2 are 1.2.1, 1.2.2, 1.2.3, 1.2.4, 1.2.5, etc. Each person's number starts with his parent's number and adds a digit to represent his position in the family. Thus if a person has the number 1.1.2.1.2. he is in the fifth generation (there are five groups of digits), and he is the second child of the first child of the second child of the first child of the starting person.

If there are more than 9 children in a family the numbering continues on with double digits, 10, 11, etc. Thus person number 1.11.2.14 is in the fourth generation and is the 14th child of the second child of the 11th child of the starting person.
