She was the first wife of the tenth Sikh Guru, Guru Gobind Singh. The couple married on 21 June 1677 and had three children together. Mata Jito was the mother of Jujhar Singh, Zorawar Singh and Fateh Singh but was not the biological mother of Ajit Singh, who was the son of Mata Sundari.

Mata Jito, also called Mata Jeet kaur was first wife of Guru Gobind Singh Ji. She was the daughter of Bhai Harijas, a Subhikkhi Khatri of Lahore. The betrothal had taken place in 1673. The father-in-law had desired that the bridegroom should come at the head of a marriage party to Lahore where the ceremony should be performed with due dignity.

The fateful events leading to the martyrdom of Guru Tegh Bahadur intervened, and in the changed circumstances it was not possible for the young Guru to go to Lahore. Therefore a temporary encampment was raised near the village of Basantgarh, 10 km north of Anandpur, and named Guru ka Lahore where the nuptials were held on 23 Har 1734 Bk/21 June 1677.

On 30th March 1699, Guru Gobind Singh created Khalsa at Anandpur. He declared that this Khalsa will be both Saints as well as Soldiers. When Gobind Singh was preparing amrit (nectar) for initiating the Khalsa, on this occasion , stirring clean water in an iron bowl with a Khanda or double-edged sword, Mata Jitoji, as the tradition goes, came with sugar crystals which were dropped into the vessel at the Guru's bidding. Sweetness was thus added to the alchemy of steel. Mata Jito ji was the first Khalsa Woman.

Three sons were born to Mata Jito ji — Jujhar Singh (14March 1691), Zorawar Singh (17 November 1696) and Fateh Singh (25 February 1699).
