Some sects of Embranthiris have adopted the Malayali Brahmin surnames "Namboothiri" and "Potti" after arriving in Kerala.
All these places are in and around one of the strongest Namboothiri Graamams (villages) of those days, Perinchelloor (near today's Taliparamba in Kannur district in north Kerala).
These Brahmanas are both Shaivite and Vaishnavite in orientation and place emphasis on performing Yajnas like the Namboodiris and speak Malayalam exclusively.
Most early Malayalam-speaking Embrandiris are followers of only the Smarta-Srauta Karmas prescribed to a Brahmin and do not align with any school of thought.
Later Brahmins who migrated from Tulunadu into Kerala have large segments of the followers of Dvaita Vedanta of Madhvacharya among them, and are ardent devotees of Lord Vishnu.
