Hi, I think what you mean is did they have babies. The Bible gives us a detailed explanation for the beginning of human life that is unique and should be respected as just that, since Adam and Eve were the only humans ever created directly by God as told in the Biblical story of Genesis.
You wish to know if a family was on earth that was never mentioned in the Bible? That would be no since the intentions of creating the two people as mates would be to start life from reproduction only and God was not hiding something and refusing to tell. Scientific discovery can be a really important thing for explanation but without guidance it can be a place of wild speculation. So, in respect for the Biblical story of creation: "In the beginning God created the heavens and the earth".
Modern English Version (MEV)
28 God blessed them and said to them, “Be fruitful and multiply, and replenish the earth and subdue it. Rule over the fish of the sea and over the birds of the air and over every living thing that moves on the earth.”
