Mata Sundriji was the daughter of Bhai Ram Saran, a Kumarav Khatri of Bajwara, in present-day Hoshiarpur district of the Punjab.
She was married to the tenth Sikh Guru at Anandpur on 4 April 1684.
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.
Mata ji received Amrit at the 1699 Vaisakhi Amrit Sanchaar ceremony and adopted the name ‘Sunder Kaur’.
