Bebe Nanaki Ji was the elder sister of Guru Nanak Dev Ji, born about five years before him. She is described in the tradition as the first person to recognise what he was, before he had said anything to anybody.
She was married to Jai Ram, an official at Sultanpur Lodhi, and it was through him that the Guru got the post at Daulat Khan Lodhi's storehouse. The fourteen years at Sultanpur, the Kali Bein, the disappearance and the return all happen in her household.
She is called the first Sikh. The claim is made in Sikh tradition and is not a formal doctrine, and it is worth stating because the first person to accept Guru Nanak Dev Ji as a teacher was a woman and his own sister.
Gurdwara Bebe Nanaki at Sultanpur Lodhi and Gurdwara Bebe Nanaki at Dera Baba Nanak mark her.
She died in 1518, before her brother, at Dera Baba Nanak.
She was five years older than her brother, and the tradition holds that she recognised what he was before anybody else did, which is why she is called the first Sikh.
She and her husband brought him to Sultanpur Lodhi, where the work at the granary and the disappearance into the Bein both happened. The first years of the teaching were spent in her household.
Gurdwaras at Dera Baba Nanak and at Sultanpur Lodhi are associated with her, the Sultanpur one standing where her house is said to have been.
