The name of the esteemed woman who was the wife of Ertuğrul Gâzi and mother of Osman Gâzi is “Hayme Ana”, and her grave is in the Çarşamba village of Kütahya’s Domaniç district. Sultan Abdülhamid II, who had the Ertuğrul Gâzi Tomb repaired, also had the Hayme Ana Tomb as good as rebuilt in the same years. Therefore, the grave in Söğüt said to be of Halime Hâtûn, must belong to another deceased.”
