The History of Humāyūn (Gulbadan Begam) 27: XXI. Babu agha (Mama agha).

27

Professor Blochmann writes the name Babu, but Babu, darling, or Banu, lady, would seem more appropriate for a Persian woman.
She was the wife of Shihabu-d-din Ahmad Khan Nishapuri, and was related to Hamida-banu Begam, Akbar's mother. Abu'l-fazl calls her Mama agha. He says that she was a good woman, and that on her death Akbar went to her house and offered condolence because of her relationship to his mother. Shihabu-d-din was damad of Maham anaga, and as damad is presumably used here in its more common sense of ‘son-in-law,’ Babu agha would seem to be a daughter of Maham anaga.
