I'm confused is she really the mother of Hunter or was that Biden's first wife who lost her life

in a car accident when they were going through a divorce? I really don't know. Original Biden's and their babysitter who later became his wife. I don't know. Where does Hunter's sugar daddy come in? Or the daughter who took showers with Joe? How about Hunter's stripper babe and mother of one of his children? Very baffling.
