Chiranjiva Sen was a resident of Srikhanda, whose wife's name was Sunanda. They had two sons, the older was Ramachandra, the younger Govinda. Ramachandra was a disciple of Srinivas Acharya who took the title Kaviraj. His siddha name was Karuna Manjari.
(Verses quoted in Gaudiya Vaisnava Abhidhana)
After the death of his father, Ramachandra went to live in Kumar Nagar with his maternal grandfather, Damodar Kaviraj, who was a disciple of Narahari Sarkar. Later he went with his younger brother Govinda to live in the village of Telia Budhari in Murshidabad district. This place has the distinction of being his Sripat.
Paramananda Bhattacharya, an ocean of love, Jiva Goswami and the other residents of Vraja, listened to Ramachandra recite his own poetic compositions and they joyfully awarded him the title of kaviraja. Ramachandra Kaviraj was full of all virtues and Narottam Das' second self.
Kamsari Sen, Rama Sen, Ramachandra Kaviraj, and the three Kavirajs, Govinda, Sriranga and Mukunda, are Nityananda's branches.
(Chaitanya Charitamrita 1.11.51)
Ramachandra wrote several books, including Smarana-camatkara, Smarana-darpana, Siddhanta-candrika, and Srinivasa Acaryera Jivana-carita.
Ramachandra's friendship with Narottam Das Thakur has been immortalized by Narottam Das' prayer to Srinivas Acharya for his association:
daya kara sri-acarya prabhu srinivasa ramachandra sanga mage narottama dasaRamachandra's disappearance day is the Krsna triya in the month of Magh. He passed away in Vrindavan after the disappearance of Srinivas Acharya.
"Please be merciful, Prabhu Srinivas Acharya! Narottam Das begs for Ramachandra's association."

"I pay my obeisances to Narottam and Ramachandra, who are devoted to all those who have dedicated their lives to the Supreme Lord, who help people cross over the ocean of material life, who know all the scriptures completely and have understood all the transcendental doctrines, who most generously distributed bhakti-rasa and won the hearts of the atheists, who are deeply attached to each others' affectionate company."
(Sangita-madhava-nataka, quoted at Bhakti-ratnakara 1.277)
