I'm working on improving the family tree generator from Life Manager mod to give you customization options so that the generated tree will be exactly how you like it. 🌳👨👩👦👦 This is currently work on progress and will be released when ready, hopefully not too long from now.
the family tree the production crew uses for reference on set has jace and baela as married (it's also missing some stuff so take it with a grain of salt)
