This is a very simple trait to track your legacy families. It is inherited from parent to child and all it does it give them a trait called Family Member so that you will know which sims your sim is related to after you've lost track, or just to have it there. There is no added effect from being near family--your sims can have a close or difficult relationship without this trait affecting your story.
For your founder (or any sim you're applying it to manually), you can find the Family Member reward trait in the reward store for 100 Satisfaction Points, or you can cheat it on to them (for example, by using MCCC > MC CAS, or you can turn on testing cheats and use the cheat 'traits.equip_trait amethyst_lilac:family_member_reward_trait_basic').
Then, when they have biological children, they will inherit the trait. From Owen down to baby Tabitha.
If you use Show/Search Sim Info (updated by Frankk), you can search all sims in the world to find your family.
The trait is Base Game Compatible and has no custom strings, so it should already be translated to all languages.
To have the trait appear in the reward store or be inheritable, you NEED Lot51's Core Library. Otherwise you will need to cheat the trait on, and it will be cosmetic only (no inheritance). But if you want to use it for that, feel free.
It DOES apply to science babies.
It does NOT apply to pre-existing children, children made in CAS, adopted children, or relationships created in any other way then birth or science baby, but you can manually add the traits to them in live mode.

Thanks to:
- The RivRel mod (long broken and abandoned now) for giving me the original idea, even though it wasn't quite what I wanted.
- Lot51's TDesc Builder and to Sims 4 Studio, which I used to make the trait.
- Waffle on discord for helping me get the last piece I couldn't figure out on my own.
Updates:
- March 15, 2024: Thanks to recent changes to Lot51's Core Library, the requirement for Mal22's Trait Tracker Injector has been removed. Now requires Lot51's Core Library only.
