Cain's family all died in the flood.
And everyone on earth are Seth's descendants, because Noah was a descendant of Seth(1Chronicles 1:1-4) and all humans on earth came from Noah's sons, Shem, Ham and Japheth.

Ion. Enosh is the son of Seth and would therefore be Cain's nephew.
Cain and Abel were the only two sons of Adam and Eve in the Bible. Cain killed his brother Abel and was forced to wander the earth.ANOTHER ANSWER:The "third son" of Adam recorded in the Bible was "SETH." But Adam's genealogy doesn't detail an exact number of Cain and Abel's MANY OTHER BROTHERS:"When Adam was 130 years old, his son Seth was born, and Seth was the very image of his father. After the birth of Seth, Adam lived another 800 years, and HE HAD OTHER SONS AND DAUGHTERS." (Gen.5:3-4 NLT New Living Translation)The only question that remains is: "How many children [sons and daughters; brothers and sisters of Cain and Abel] is it possible for a man have in the course of 800 years?"
Enos, son of Abel's younger brother Seth, was Abel's nephew. Cain had already slain Abel by the time Seth was born.
Cain, Abel,and Seth were their sons,but Cain killed Abel out of jealousy.
Seth had no grandmother. He was the 3rd son of Adam and Eve, born after Cain killed Abel.
In the book of Genesis it is stated that Adam had other sons and daughters, so family can go on.
Cain, Able, and Seth
