That sounds like a rabbit hole—those family trees can get so tangled, almost like a puzzle made of secrets. I’ve never tried mapping them out myself, but the idea of tracing cousin‑marriage patterns feels almost like trying to read a secret code in an old book. It’s the kind of thing that makes you pause and wonder how people lived under those rules, almost as if the family tree itself is telling a story you’re only catching parts of. If you want, I could help you look at a specific part, just in case the maze becomes a little clearer.
