I played a card game with my family called "Sergeant Major" growing up. Years later, I've finally googled this game, and there's definitely a game by that name, but what we played is *not that*.
I could not google-fu my way to a single card game that matches what we played.
I find it so cool and weird that I know a card game rare enough I can't find it online.
@ek my dad’s side of the family plays a variant of rummy called “concentration” which is nothing like the memory game that most of the world calls that
