CC Ādi 10.34
prathamei nityānandera yāṅra ghare vāsa
Sadāśiva Paṇḍita, the twelfth branch, was always eager to serve the lotus feet of the Lord. It was his good fortune that when Lord Nityānanda came to Navadvīpa He resided at his house.
It is mentioned in the Caitanya-bhāgavata, Antya-khaṇḍa, chapter nine, that Sadāśiva Paṇḍita was a pure devotee and that Nityānanda Prabhu resided at his house.
