Mods are fan made DLC and game enhacements. You can find them at nexusmods if you play on PC, or if you are playing Skyrim Special Edition on Xbox One or PS4 there is a mods menu in the start screen.

There might be a mod that can make those and other characters marriage candidates on Nexus. I don't know if there are any marriage mods for Xbox One or PS4 though.
