the following paragraph in jahangirnama clearly indicates that mariam uz zamani is not his mother.jahangir's mother is someone else (not named) and lives in lahore, not in agra or delhi.
p 76 JAHANGIR WAITS UPON HIS MOTHER.
As when I started in pursuit of Khusrau I had left my sonKhurram in charge of the palaces and treasury, I now, when that affair had been settled, ordered the said son to attend uponHazrat Maryam-zamani and the other ladies, and to escort them to me. When they reached the neighbourhood of Lahore, on Friday the 12th of the month mentioned, I embarked in a boat and went to a village named Dahr to meet my mother, and I had the good fortune to be received by her. After the performance of obeisance and prostration and greeting which is due from the young to the old according to the custom of Chingiz, the rules ofTimur and common usage, and after worship of the King of the World (God), and after finishing this business, I obtained leave to return, and re-entered the fort of Lahore.
