In 1966, while in law school, Biden married Neilia Hunter. They had three children, Joseph R. “Beau” Biden III, Robert Hunter, and Naomi. His wife and infant daughter died in a car accident shortly after he was first elected to the US Senate in 1972 and his two young sons, Beau and Hunter, were seriously injured in the accident, but both eventually made full recoveries. Biden was sworn into office from their bedside. __
