RAI BULAR, a Muhammadan noble of the Bhatti clan, was during the latter half of the fifteenth century the chief of Talvandi Rai Bhoi, the village where Guru Nanak was born in 1469. Rai Bular had great affection for young Guru Nanak and held him in high esteem. According to Janam Sakhi accounts, Rai Bular perceived the Divine in Guru Nanak and became a devotee. Once young Nanak was arraigned before him for having allowed the cattle herd he was tending to damage a farmer`s crop.
SHIV RAM (b. 1418), grandfather of Guru Nanak, was the son of Ram Narain, a Bedi Khatri. He and his wife, Banarasi, lived in a village called Patthevind, now the site of Gurdwara Dera Sahib, 10 km east of Naushahra Pannuan in present day Amritsar district of the Punjab. Two sons, Kalu and Lalu, were born to them the former in 1440 and the latter in 1444. The elder, Baba Kalu, variously mentioned by chroniclers as Mahita Kalu, Kalian Rai, Kalu Rai, Kalu Chand or Kalian Chand, was the father of Guru Nanak.
