His father Kalyan Chand Das Bedi was a patwari employed by a local Muslim landlord Rai Bullar Bhatti. His mother's name was Mata Tripta, and his sister Bibi Nanaki became a spiritual figure in her own right.
Guru Nanak was married to Mata Sulakhni at about 16 years of age. His marriage to her took place in the town of Batala. The couple had two sons, Sri Chand, who later set up the Udasin sampradaya, and Lakhmi Chand.
Rai Bular, the local landlord and Guru Nanak's sister Bibi Nanaki were the first people who recognised divine qualities in the boy.
