That's true, but assumes you have the checklist of what data to analyze in hand when you start out. If you only decide after the fact which familial relationships have interesting trends, you'd have to start over again. It seems more reasonable to start by transcribing everything to text, annotating that text, and then running a lot of scripting to automatically query that data.
