Ancient Arabs are from Aram.
Another line of Salih PBH from my sunni book on shari a(Reliance of the Traveller)
is SaaliH ibn Ubayd ibn Asif ibn? Masih ibn Ubayd ibn Hadhir ibn Tamud(Thamud) ibn Ghabir(Ather,Gether) ibn Iram(Aram) bin Sam ibn Nuh PBH
So Allah sent unto them His Prophet Salih , a man from among them. His name was Salih Ibn 'Ubeid, Ibn Maseh, Ibn 'Ubeid, Ibn Hader, Ibn Thamud, Ibn? Ather(gether), Ibn Eram(Aram) ibn Sam(Shem) Ibn Noah. He called his people to worship Allah alone, and to not associate partners with Him. While some of them believed? him, the majority of them disbelieved and harmed him by both words and deeds. Salih directed them: "0 my people! Worship Allah, you have no other Ilah (god) but Him." Surah 11: 61
Prophet HudPBH ibn Abdullah ibn Rabah ibn al Khulud ibn? Ad ibn Uz ibn Aram(Iram) ibn Sam(Shem) ibn Nuh(NOAH)PBH
so the ancient arabs Aad are from UZ and the ancient Thamud who came after them are from GETHER which means Prophet Hud PBH(Uz) & Prophet SaaliH PBH(Gether) are from Aram bin(son of)Sam(Shem) and the syrians and Arameans are from Aram as well.
