LoveJoe Biden's first marriage. Neilia Hunter was an American teacher and her husband's exact contemporary — both born in 1942. They had three children together: Beau, Hunter and Amy. Neilia died in 1972 in Hockessin, Delaware, the year Biden was first elected to the Senate. He later married Jill Biden, but the first family remained its own chapter: Beau and Hunter grew up public figures, and Neilia's name stands first in his marriage record.
