The Tarins should not be confused with the Tarans, who belong to the Ghurghusht division of the Afghans, being descended from a Syed Tahir, turned into Taran by the Afghans. He (Tahir) was adopted by Kakar.
The Spin Tareens were originally settled in Pishin, but leaving their home they migrated southwards to the Shahrig Tehsil of Sibi district, and Sanjawi and Duki Tehsils of Loralai district. The principal section in Sanjawai Tehsil are the Wanechis, who occupy parts of Wani, Chauter and Shirin valley. The principal sections of Spin Tareen in Duki Tehsil are Lasiani, Marpani, Semani, Adwani and Saam.
Tor Tareen is credited by local tradition with having had a son, Babo, who in turn had two sons, Ali and Haroon. The descendants of Ali are known as Alizai, whilst those of Haroon are divide into five principal sections found in the Pishin Tehsil. The hereditary governorship of Pishin under the Afghans long rested with Batezai branch of the Abu Bakar sub-section of the Harunzais, and as a consequence the Batezais of Pishin claim social superiority among their fellows. According to local accounts, the Umarzai Tareens came from Pishin to Smallan where the Wanechis gave them the Shinlez lands. They couldnt hold their own against Spin Tareens and proceeded to Duki,which place they took by force from Nisai-spin Tareens who had to fly to Calcutta and Barwan.
