After personally carrying out an investigation, Buchanan Hamilton has recorded a brief history of Nityananda's family in the Purnea Report.
Nityananda Prabhu was born on the thirteenth day of the bright fortnight of Magha (Feb.-March) in the village of Ekacakra in the district of Birbhum in 1395 Saka (1473 AD). His father was Hadai Pandita (Hado Ojha) and his mother was Padmavati. His paternal grandfather, Sundaramalla Nakadi Baduri was a brahmana of the Radha clan.
Nityanda's past name was Kuvera and He was an avadhuta. Steven Rosen (Satyaraja das) says in his book Panca-tattva, 3.13:"Nityananda was considered an avadhuta sannyasi, although it is said that He never formally adopted sannyasa order. Avadhutas (the pure ones, in SB 4.29.11 p. called "most free") are usually associated with the Saivite tradition but there is a little known branch of Vaisnava sannyasis known as turiyatit-avadhuta. They are described in the Narada-parivrajaka-upanisad, Turiyatit- avadhuta-upanisad and the Brhad-avadhuta-upanisad."
In the same book (3.40) he lists twelve gopalas, associates of Sri Nityananda, with their identity in Caitanya-lila:Sridama (Ramadasa Abhirama of Khanakul-Krsnanagar in Hooghly)
Sudama (Sundarananda Thakura, brahmana ascetic)
Subala (Gauridasa Pandita)
Mahabala (Kamalakara Pipalai)
Subahu (Uddharana Datta)
Mahabahu (Mahesa Pandita)
Arjuna (Paramesvara Dasa)
Dama (Purusottama Nagara)
Labanga (Kala Krsnadasa)
Madhumangala, or Kusumasava (Sridhara)
Sri Nitai is Isa prakasa (CC 1.1.7-11), the cherished goal of Gaudiyas (CC 1.1.18-19), and is depicted as the trunk of the tree of bhakti (CC 1.9.21, 1.10.115)
His childhood sports up to twelve years of age are described in CBh. 1.9.12-99; His pilgrimage tours up to twenty years of ages in CBh. 1.9.100-136; His arrival in Navadvipa at the house of Nandana Acarya and his meeting Lord Caitanya is described in CBh. 2.3.120-2.4.76.
Premavilasa narrates the following information relating to Nityananda Prabhu: marriage of Nityananda; settled life at Khardaha with Vasudha-Jahnava; death of seven sons soon after birth when Abhirama conveyed his humble obeisances to each; birth of Viracandra and Ganga later; both stayed alive and healthy despite Abhirama's offering of obeisances; hymns sung by Abhirama in praise of Ganga devi.
