I am developing a geneaology application, and am currently at the stage of modelling relationships between individuals.

Based on my research, I have noted that most of the mappings of relationships are based on families (father + mother) and so I would like to understand the underlying reasoning behind this before I adopt it blindly.

Since my project is patriarchal, I assume that as soon as a person adds a father, then that creates a new family
