Didn't Hunter Biden's birth certificate indicate that in addition to their living son (Beau), there had been another child which did not come to term? It doesn't state when this occurred. Beau and Hunter are a day more of exactly a year apart, it is doubtful it happened then, and certainly not in the period during which she carried Beau, who was born on February 3, 1969. They married in August of 1966, and Beau wasn't born until 1969. Was this other child someone else's baby?
