Who dated Mahfiruz Hatun?

Hatice Mahfiruz Hatun or Mahfiruze Hatun (Ottoman Turkish: ماه فروز خاتون, "glorious moon" or "daytime moon" or "turquoise moon"; c. 1590 – disputed) was a concubine of Ottoman sultan Ahmed I and mother of his firstborn son, Osman II.

Ahmed I (Ottoman Turkish: احمد اول Aḥmed-i evvel; Turkish: I. Ahmed; 18 April 1590 – 22 November 1617) was the sultan of the Ottoman Empire from 1603 to 1617. Ahmed's reign is noteworthy for marking the first breach in the Ottoman tradition of royal fratricide; henceforth, Ottoman rulers would no longer systematically execute their brothers upon accession to the throne. He is also well known for his construction of the Blue Mosque, one of the most famous mosques in Turkey.
