Guhas mostly belong to Kayastha caste in Bengal. The Bengali Kayasthas evolved as a caste from a category of officials, between the 5th/6th century AD and 11th/12th century AD, its component elements being putative Kshatriyas and mostly Brahmins. Guhas (and Guhathakurtas) are considered as Kulin Kayasthas of Kashyapa gotra, along with Boses, Ghoshes and Mitras.
