Travancore Iyers
Some of the Travancore Iyers were the original residents of Travancore. There were some Iyers in Venad which later on grew to be the Travancore state. Shungoonny Menon calls them Native of Travancore.
There has also been a continuous inflow from Thirunelveli and Ramnad districts of Tamil Nadu which are contiguous to erstwhile princely state of Travancore. Many parts of the present Thirunelveli district were part of the old Travancore state. Some of these migrated to Cochin and later to Palakkad and Kozhikode districts.
During the rule of Travancore kings, many Iyers (Tamil Brahmins) were invited to Thiruvananthapuram for participating in rituals related to Padmanabhaswamy Temple. These migration continued for decades, and thus Iyer population is concentrated around this temple in Trivandrum.
Unlike Palakkad Iyers, Travancore Iyers language is more Tamil with only a slight mix of Malayalam words.
