Analysis of information sources in references of the Wikipedia article "Rohilla" in English language version.
The designation Rohilla developed during the seventeenth century as a fairly broad notion of the people coming from Roh or Rõh, corresponding roughly with the mountainous terrain of the eastern Hindu Kush and the Sulaiman Range. Only in the seventeenth-century Indian and Indo-Afghan works do we find Roh frequently used as a more specific geographical term which corresponded with the territory stretching from Swat and Bajaur in the north to Sibi and Bhakkar in Sind, and from Hasan Abdal in the east to Kabul and Kandahar in the west.
The nomenclature ' Rohilkhand ' gained currency particularly after Ali Muhammad Khan, the adopted son and successor of Daud Khan defeated Raja Harnand and occupied Katehr in 1742
Amongst other prisoners he obtained a young Jat boy of eight years . Daud took a fancy to him and adopted him as his son and named him ' Ali Muhammad Khan.
Dunde Khan; Fateh Khan retained possession of Budaun and Usehat, while Abdullah Khan ( Ali Muhammad's son ) was established in possession of Ujhani and Sahaswan . Kot was given to Sardar Khan and Salempur was kept by Hafiz Rahmat
