Continuing from my earlier suggestion regarding property of houses, I think it’d be cool to have families! Basically, any Hearthlings with the same surname (or other definable settings) could be members of a family together, and would be prone to working/eating/sleeping near each other given no other player-created motives. They would also be prone to talking together more often than Hearthlings that are strangers.

Could improve morale or gain some kind of reward for having families etc, the same way you are rewarded by morale for having food
