Recently, three coins minted by Osman I in Yenişehir-Bursa during his reign which reads "Osman bin Ertuğrul bin Gündüz Alp" proved that the name of the father of Ertuğrul was Gündüz. However, according to some other sources by Neşrî, Hasan bin Mahmûd el-Bayâtî, and Âşıkpaşazâde the name of the son of Ertuğrul and the brother of Osman Gazi was Gündüz Alp, as well.

Gündüz in the family tree of Ertuğrul and Osman

The grandfather of Osman Beg was mentioned in various sources as Gök Alp, Gündüz Alp and Süleyman Şâh.
According to 15th century Ottoman writers Enveri and Karamani Mehmet Pasha, Gündüz Alp is the father of Ertuğrul. Yazıcızâde Âli's Tevârih-i Al-i Selçuk indicated Gök Alp, the brother of Gündüz Alp as the father of Ertuğrul. Some other writers in their published works like 14th ceuntury historian Şükrullah's , Hasan bin Mahmûd el-Bayâtî's Câm-ı Cem-Âyîn, Âşıkpaşazâde's :tr:Tevârîh-i Âl-i Osman |History of Âşıkpaşazâde, and Neşrî's :tr:Kitâb-ı Cihannümâ|Kitâb-ı Cihannümâ had asserted that Süleyman Şah was the father of Ertuğrul. Halil İnalcık argues that the latter have confused Süleyman Şah with the grandfather of Gündüz Alp, namely Mir Süleymân Alp. Three coins which read "Osman bin Ertuğrul bin Gündüz Alp" supports the view that Gündüz was Ertuğrul's father.
