Adds the following types of family relations to the game:
  • Nth Cousin (e.g., 2nd Cousin)
  • Nth Cousin N× Removed (e.g., 2nd Cousin 1× Removed)
  • Half-Cousin
  • Nth Half-Cousin (e.g., 2nd Half-Cousin)
  • Nth Half-Cousin N× Removed (e.g., 2nd Half-Cousin 1× Removed)
  • Half-Aunt/Uncle
  • Half-Niece/Nephew
  • Great × N Aunt/Uncle (e.g., Great-Uncle, Great-Great-Uncle, etc.)
  • Great × N Niece/Nephew (e.g., Great-Nephew, Great-Great-Nephew, etc.)
  • Great × N Half-Aunt/Uncle (e.g., Great-Half-Uncle, Great-Great-Half-Uncle, etc.)
  • Great × N Half-Niece/Nephew (e.g., Great-Half-Nephew, Great-Great-Half-Nephew, etc.)
  • Great × N Grandparent (e.g., Great-Great-Grandfather)
  • Great × N Grandchild (e.g., Great-Great-Grandson)
  • Half-Sibling-In-Law
  • Grandparent-In-Law
  • Grandchild-in-Law
  • Great × N Grandparent-In-Law (e.g., Great-Grandfather-In-Law, Great-Great-Grandfather-In-Law, etc.)
  • Great × N Grandchild-In-Law (e.g., Great-Grandson-In-Law, Great-Great-Grandson-In-Law, etc.)

This scales infinitely or up to a limit set in the tuning (for example, a Sim could have a 5th Half-Cousin 4× Removed).

Also allows adding restrictions to romance between Sims the player feels are too closely related. By default, the restrictions regarding romantic interactions between Sims are the same as EA's.

Additionally, relation names for SimBots follow the same scheme as those for Plumbots (for example, a SimBot's creator is now referred to as "Creator" instead of "Mother" or "Father"). This can be reverted in the tuning.

(Since 2025/09/21)
There is now support for assigning family relations between Sims without other Sims to fill in the gaps. One can add ancestors, descendants, siblings, siblings of ancestors, descendants of siblings, cousins of any degree, cousins of any degree of ancestors, and descendants of cousins of any degree. The interaction for assigning relations can be enabled by changing the tuning value "kShowCheatInteractions" to "True" (see below for where to find that setting); the interactions will show up on the target Sim (the one clicked on) to assign relations between them and the selected Sim (the one with the Plumbob over their head). Family tree visualization will be supported in the future. If there are any performance and/or stability issues in your game, download the "Legacy" version of the mod and use it instead until said issues are fixed.

Settings regarding enabling cheats for assigning relations, restrictions on romantic interactions, and what types of relations can be shown can be changed by using s3pe to edit the "Tuning" _XML resource in the mod's .package file, or by using NRaas' Retuner to change the settings under General > By Tunable XML > Sims3.Gameplay.Destrospean > ExpandedGenealogy.
