Include Cousins, Uncles, and In-Laws as Family

I would like cousins up to the 3rd degree or generation, uncles, and the spouses of uncles to be recognized as family so they can be invited to family gatherings. In some way, the game already acknowledges these ties since it does not allow marriages between cousins; however, this relationship does not always appear as “family” in certain situations, such as family dynamics. The in-laws or the spouse’s parents should also be considered family.
