The origins of this Misl are linked to Sadao Singh who founded the villages of Ahlu, Hullu-Sadho, Tor and Chak.
Sadao was from the Jatt caste. Sadao Singhs younger brother, Sadawa, fell in love a girl from a Kalal caste - Distillers. The families did not approve. Upon seeing the immense love the two had the families agreed to the marriage on the condition that all children will be married into the Kalal caste. Sadawa agreed to this. This is how the villagers of Ahlu started to be known as Kalals.
Sadawa fathered 4 children, One was called Gopal. Dewa Singh was born to Gopal. Dewa Singhs son Badar Singh was married to the sister of Bagh Singh, a zamindar from the district of Lahore.
Jassa Singh was born on May 3rd 1718. At the age of 5 his father passed away.
His mother took him to Delhi where Mata Sundri Ji was, and remained there for a few years.
At 7, his Mama, Bagh Singh, asked Mata Sundri Ji if he can have Jassa Singh so he can succeed him, as Bagh Singh had no children of his own.
Bagh Singh had under him many captured villages and was given tributes by other Zamindars.
Nawab Kapoor Singh met Bagh Singh and took Jassa Singh under his care. Kapoor Singh Ji was one of the Panj Pyaare that gave Pahul to Jassa Singh.
Jassa Singh was given the duty of distributing grain for the horses owned. Jassa Singh was resentful of his role, but Nawab Kapoor Singh Ji explained that he soon will have a greater responsibility.
Jassa Singh was treated like a son by Nawab Kapoor Singh Ji.
Jassa Singh was raised in Delhi mainly, where he had picked up Urdu and had the habit of mixing Urdu with Punjabi. The Sikhs would often tease Jassa Singh and call him "Hum Ko - Tum Ko".
When Nawab Kapoor Singh Ji was told, they would reassure Jassa Singh and say "Why should you mind what the Khalsa say? They got for me a Nawabship, and might make you a Patshah." The Sikhs at once caught up the words as a prophecy, and began to call Jassa Singh a Patshah.
At 13 Jassa Singh lost Bagh Singh, and inherited his property.
His “political talent, religious zeal and lofty aspirations combined, rendered him one of the most powerful federal chiefs of the Punjab.”
Jassa Singh Ji was a brave youngman, and many Sikhs believed to get pahul by Jassa Singh was a privilege. Many prominent Sikhs received pahul by Jassa Singh, one being Raja Amar Singh, Phulkian family.
