Analysis of information sources in references of the Wikipedia article "Ertuğrul" in English language version.
The problem of Ottoman origins has preoccupied students of history, but because of both the absence of contemporary source materials and conflicting accounts written subsequent to the events there seems to be no basis for a definitive statement.
No source provides a firm and factual recounting of the deeds of Osman's father.
....suggests that Ertuğrul was a historical personage
Reliable information regarding Osman is scarce. His birth date is unknown and his symbolic significance as the father of the dynasty has encouraged the development of mythic tales regarding the ruler's life and origins
In the tomb's garden, there is a grave belonging to Ertuğrul's wife, Halime Hâtûn. However, here there must be some information mistakes. 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.
