クリシュナ・ラージャ4世
The name Jayalalithaa was adopted at the age of one for the purpose of using the name in school and colleges. It was derived from the names of two houses where she resided in Mysore. One was "Jaya Vilas" and the other "Lalitha Vilas". Her paternal grandfather, Narasimhan Rengachary, was in the service of the Mysore kingdom as a surgeon, and served as the court physician to Maharaja Krishna Raja Wadiyar IV of Mysore. Her maternal grandfather, Rangasamy Iyengar, moved to Mysore from Srirangam to work with Hindustan Aeronautics Limited. He had one son and three daughters—Ambujavalli, Vedavalli and Padmavalli. Vedavalli was married to Jayaram son of Narasimhan Rengachary. The couple Jayaram-Vedvalli had two children: a son Jayakumar and a daughter, Jayalalitha. Her mother, her relatives and later co-stars and friends referred to her as Ammu.
