Looking for a personal relationship CRM

I've been playing with one called Monica, but I must say I'm pretty disappointed in the lack of basic features one would expect from a relationship tracker/CRM. I'm looking for an alternative I can host myself, which is why I was drawn to Monica to begin with, but I need one with inferred relationships, and a family tree would be nice. Is there anything out there like that or that I can modify with plugins/addons to support those types of features? Thanks for reading 🙂
