Rabia Bala Hatun

Râbi'a Bâlâ Hâtun (; died January 1324 birth name "Rabia") was the second wife of Ottoman Sultan Osman I. She was the daughter of the famous Sheikh Edebali and the mother of Alaeddin Pasha of the Ottoman Empire. Her identity is frequently confused with the mother of Orhan Bey, Malhun Hatun.
Names.
Edebali's daughter is called by different names in the sources, Rabia and Bala, suggesting that these may have been the names of other wives. Sheikh Edebali's daughter is referred to as "Rabia" in the history of Uric, and as "Malhun" in those of Aşıkpaşazade and Neşri. The latter tradition has proved dominant, and Orhan's mother Malhun Hatun, the daughter of Ömer Abdülaziz Bey, is commonly thought to be Sheikh Edebali's daughter. The 1324 investiture deed for a dervish monastery built by Sultan Orhan suggests that his mother was not, as popular historical tradition holds, the daughter of Edebali, but Malhun Hatun, the daughter of one "Umar Bey or Ömer Bey". The title "Bey", used by the princely dynasties of Anatolia, suggests that Malhun Hatun's father was a person of certain status and authority.
Marriage to Osman.
The marriage of Osman and Rabia Bala Hatun occurred in 1289. From the central government records regarding the property she received at the time of her marriage; the village of Kozağaç in the district of Bilecik, where the dervish hospice of her father was located. Edebali was an influential religious leader in the Ottoman territories.
Death and burial.
She died in 1324. Although she preceded her husband, Osman, she was buried with her father in Bilecik.
