In Genesis, Chs 5 and 10, we are told:
The sons of Noah were Shem, Ham and Japheth
The children of Shem were Elam, Asshur, Arphaxad, Lud and Aram
The sons of Ham were Cush, Mizraim, Phut and Canaan
The sons of Japheth were Gomer, Magog, Madai, Javan, Tubal, Meshek and Tiras
All people alive today are descendents of Noah and his family.
