Millénaire is a mod for anyone looking to fill Minecraft‘s empty areas with villages based on “loose 11th-century Norman, North Indian and Mayans themes” (it’s also for anyone dissatisfied with the game’s lackluster native ones). Those villages come replete with adults as well as children capable of trading with you, raising crops, tweaking buildings, harvesting lumber, creating tools and generally expanding their living areas. Trade with them and they might reward you with special items, or even build you a house.
