ابن خلكان
His name was Abū Naṣr Muḥammad b. Muḥammad Farabi, sometimes with the family surname al-Ṭarḵānī, i.e., the element Ṭarḵān appears in a nisba. His grandfather was not known among his contemporaries, but a name, Awzalaḡ, suddenly appears later in the writings of Ibn Abī Uṣaibiʿa, and of his great-grandfather in those of Ibn Khallikan.
