Roxana, concubine/(second Haseki?) of Murad IV
Mourad had resolved upon undertaking a great campaign against Persia, when the Kislar-Aga presented him with a beautiful Circassian, about sixteen years old, who was named Roxana. Never before had a beauty so perfect adorned and illuminated the Seraglio. Her hair was of a pale gold, and deep blue eyes sparkled beneath eyelashes of the deepest jet. Her features were formed as regularly as the choicest specimen of the sculptor's art; and her complexion was of the delicate freshness which we seek to typify by the old poetical union of the lily and the rose. At first this beautiful creature attracted the Sultan by her personal charms, soon she subdued him, not by her softness, but by her hardihood and inflexible will. The sombre Mourad yielded to the ascendancy of a character more determined and more energetic than his own. While he followed "in the ranks of war," and accomplished the conquest of historic Bagdad and ancient Babylon, she governed in his name, and though she had brought him but daughters, he honoured her with the title of Hassaki. Every one in the Seraglio obeyed her; the Imperial family was at her feet; and Kiosem herself was constrained to bow her head before the haughty beauty.
The cruel Roxana caused Orcan and Bayazid, and then the ill-fated Mustapha - for whom life had worn so dark and cloudy an aspect-to be strangled, and meditated the death of Ibrahim, the youngest of the three princes, who was only rescued by Kiosem's protestations that he was an idiot. Up to this moment Kiosem had endured in silence the insults of the favourite, but now that Ibrahim alone survived of all her offspring, she began to struggle secretly against her enemy. Mourad IV returned in triumph after his conquest of Babylon. He made his public entry into Constantinople with a leopard's skin flung over his shoulders as an Imperial mantle, and surrounded by the princes whom he had vanquished. Kiosem knew that the corrupt Persians had exercised a fatal influence over him, and that a beautiful Persian had temporarily cooled his passion for the imperious Roxana. She seized the opportunity of complaining, for the first time, of the favourite's insolence. She accused her of having dared to raise her hands against a daughter of the Ottoman blood-the Sultana Mihernia, his own sister. The fact was irrefutable; many eyes had witnessed it. The exasperated Sultan summoned Roxana to his presence, and reproached her with having forgot the respect she owed to the Sultana, and the distance that separated them. Roxana, instead of replying humbly, gave vent to a torrent of reproaches and sarcasms, until her master was seized with a tiger-like fury. He seized the arms which hung at his girdle, and struck her violently on her head. Immediately her beautiful brow grew livid, her fair eyes half closed, and a violet tint overspread her lovely countenance. As she had still remained standing, it was supposed that her indignation had wrought this startling change, but she suddenly tottered, clutched her tresses wildly with her hands, and fell dead. She was but twenty-three years old.

Source "Dimensions of Transformation in the Ottoman Empire from the Late Medieval Age to Modernity - p. 72" notes that Roxana was different from Rachima - [Rachima was] sister of the defeated governor of Yerevan, Emir Gûne, with whom Murad IV had a son born in Damascus. The boy is said to have been called Şehzade Süleyman Murad (by de Chassepol) or Şehzade Alaüddin (b. 26th August 1635; by Naima). Author notes (n. 44) that Roxana accompanied Murad during İran campaign and was "extremely jealous" when Rachima became his lover.
