There are many subgroups in Brahmins based on demography. Rishiswar, Sanadhya, Kanyakubj, Telang, Saryupareen, Bhumihar, Goswami, Tyagi, and Saraswati are the main streams of Brahmin. Across the subcontinent, other Brahmins are also believed to have switched from the traditional duties of Brahmins in favor of military and administrative ones. In other parts of the subcontinent, outside of Punjab and the Gandhara region, they have been known as the Tyagi Brahman and "brahma-kshatriya" groups. These groups also claim to have descended from the Parshuram Tyagi Brahmans of Haryana and West Uttar Pradesh; traditionally, they have a close relationship and brotherhood with Mohyals.
Some Mohyal Brahmins migrated eastward and became as some sub-divisions of Bhumihar Brahmins, some of whom are also descendants of Hussaini Brahmins and mourn the death of Imam Hussain. Bhumihar Brahmins and Tyagi/ Mohyal Brahmins have an affinity and brotherhood for each other. The Bhumihar Brahmins, of whom many, though not all, belong to the Saryupareen Brahmin division of Kanyakubja Brahmins.In Kerala Ezhavathy is also a Mohyal community.
