Y-DNA Haplogroup D, sired children by Noah's 2nd wife Naamah sister of Tubalcain, children of Zillah. The original land of Cana'an was greater Syria between the river of Egypt and the Great Euphrates.
Ashur made alliance with them until being pushed out of Shinar by Nimrod's "mighty invaders" (Gibborim Philistim) of Kisleh who established a fortified boarder against Ashur along the Euphrates at Kish (Akkad), Nippur (Calneh), Uruk (Erech), and Babel (Eridu). Nimrod the titan-lord was often called son of Canaan due to his conquests. He is also called son of Cush because he inherited Kush his predecessor in dominion. The Canaanites were ultimately destroyed according to Deuteronomy 20:17 but some of his offshoot nations survived as Sino-Tibetans.
