This Rai Singh was the son of the celebrated Bhangu Jat chiefs Mahtab Singh who had boldly killed Massa Ranghar, the Governor of Amritsar. He was a member of the Karorasinghia Misl and had impressed his leader Sham Singh so much that the latter married his daughter to him. He seized a group of several villages in Samralah tahsil where his descendants still reside at Bhari and Kotla Badla. Ratan Singh, our valuable writer of Panth Parkash, was his son.
