The Padamadans ruled over the "plains" or "padam" as the plains used to be called in the local language of Malayalam (and also in root words of Sanskrit language). The "madan" or "maadan" is indicative of a superlative status: one who is in charge of, or rules over, or in divine command of.
Padamadans do not come in the royal families accredited during the formation of Republic of India and State of Kerala in 1956 as they were not active during the process yet were one of the minor royal houses in the periphery states adjacent to the major royal houses who ruled the significant territories of Malabar, Cochin, Travancore etc.
These plains of mid-Kerala would have been quite productive agriculturally. The mountains of Kerala in antiquity were dense impregnable forests. Another related etymology of the surname is the clan or family that ruled with force "in command of the armies" or "in command of the people" or "in command of the armies of the plains" which are translations of the surname . Origins show an antiquity of at least a 1000 years or so based on family stories passed down from generations. Family stories include mentions of the inquisition from west where some family members hid in the mountains to avoid persecution. They also speak of a Chinese emissary sent by the Emperor of China who stayed in Kerala for several months and showed the Padamadans the benefits of installing Chinese nets and techniques for maintaining (manually dredging) ports in the difficult coastline of this area.
