NSIS, but . . . Abel died childless (or at least there are no accounts claiming he didn't, as opposed to Cain, whose descendants are listed).
Genesis 5:4 mentions, in addition to Seth, that Adam had many sons and daughters. More interestingly, the glosses note that Cain and Abel were each born with a sister twin, and in one account one of the sisters is what they fought over when they went into the field where Cain killed Abel.
