From Dedan came the Dedanim or Dedanites, spoken of with the Arabians in Isa 21:13; Junius thinks Adada in Palmyrene of Syria had its name from this man, and in which country is the mountain Aladan or Alladadan.
Bochart more probably takes Dedan, a city in Idumea, to derive its name from him. There is a village called Adedi in the country of the Cassanites, a people of Arabia Felix, which Ptolemy makes mention of, and seems to have some appearance of this man's name:and the sons of Dedan were Asshurim, and Letushim, and Leummim; these names being plural are thought not to be proper names of men, but appellatives, descriptive of their places of abode, or of their business: hence the Targum of Onkelos represents them as such that dwelt in camps, in tents, and in islands; and the Targums of Jonathan and Jerusalem call them merchants, artificers and heads of the people: however, Cleodemus the Heathen historian is wrong in deriving Assyria from Asshurim, whom he calls Ashur; since Assyria and Assyrians are so called from Ashur, the son of Shem, Ge 10:22.
