Dear sister,
Lord Raghuvir is the family Deity of Thakur's family. There is a temple of Sri Raghuvir in RK Ashram, Kamarpukur.

Take the "virtual darshan" of this Holy pilgrimage site:

Temple of Sri Raghuvira:
This also was previously a small hut facing east. It had floor and walls of mud and a roof of straw, The present temple has been constructed exactly on the same spot with the same dimensions. In it, the Salagrama Sheela (round stone emblem) of Raghuvira (Rama), the earthen jar representing Goddess Sitala, the Rameswara Sivalinga, an image of Gopala and the Salagrama Sheela of Narayana are worshipped everyday. The last two deities were worshipped by Lakshmi Didi, niece of Sri Ramakrishna.
