In Kaverippoompattinam in the Tanjore District of Madras State, there was a
great devotee of Siva by name Sivanesar. He belonged to the mercantile community. The name
of his wife was Jnana Kalambai. A daughter was born to them.
But Sivanesar wanted to be blessed with a son. He worshipped
Lord Siva at Tiruvengadu and was at last blessed with a son. The name given to the child
by his parents was Tiruvengadar - one who was born through the grace of the Lord at
Tiruvengadu. It is said that Kubera, the Lord of Wealth, himself was born as a child.
Later the child came to be known as Pattinathar.
