According to the Indian caste system, Guhathakurta belongs to the Kulin Kayastha group, the most highly ranked group amongst Kayasthas, a sub-sect of the Kshatriya caste of Indo-Aryan origin.
Guhathakurtas trace their history back to the Sena Dynasty, which ruled Bengal during the 11th and 12th centuries. The family originates from the town of Banaripara in the Barisal District of present-day Bangladesh. Since the Partition of India in 1947, its members have resided primarily in the state of West Bengal in India.
