It was however Ravi Varma's daughters who were singled out by destiny for greatness, although not in the field of art, nor personally, but through their daughters. The three daughters of Ravi Varma and Bhageerthi Bayi were Mahaprabha Amma (who features in two of Varma's most famous paintings), Uma Amma (named after Varma's mother) and Cheria Kochamma. In 1900 CE, the Royal House of Travancore once again faced a succession crisis. Bhageerthi's two elder sisters, who had been adopted in order to carry forward the lineage, had failed to produce the desired heirs. They had six children between them, but only two of those had survived, and both were boys (who also, incidentally, later died childless). According to the matrilineal Marumakkathayam system, the succession to the throne could only progress through females, and therefore it was necessary to make an adoption. Tradition dictated that two girls belonging to branches of the Royal Family be adopted together. They would be designated the Senior and Junior Rani of Attingal, and the succession to the throne of Travancore would be vested in their progeny, in accordance with the unusual and unique Marumakkathayam system of succession.
Two of Varma's grand-daughters were marked by destiny to receive this honour, the main reason being that they were the nearest matrilineal (cognatic) kin to the incumbent Rani of Attingal. In August 1900, Mahaprabha's eldest daughter Lakshmi Bayi (aged 5 years) and Uma's eldest daughter Parvati Bayi (aged 4 years) were adopted into the Royal family of Travancore. It was Bharani Thirunal Lakshmi Bayi, their surviving grand-aunt, who formally adopted them. She died within one year of doing this, and the two girls were then installed as the Senior and Junior Ranis of Attingal respectively. They were married while yet in their early teens to two gentleman from suitable aristocratic families. It was the Junior Rani, Sethu Parvathi Bayi, who gave birth to the much-awaited heir in 1912, exactly a day after her sixteenth birthday. Incidentally, her husband was a grand-nephew of Raja Ravi Varma and belonged to Kilimanoor. The newborn child was the future Maharaja Chithira Thirunal, the last ruling Maharaja of Travancore. He was followed by a brother (the future Maharaja Marthanda Varma III) and a sister Lakshmi Bayi, the mother of Maharaja Rama Varma VII who is presently on the throne (since 2013). Meanwhile, the Senior Rani (Sethu Lakshmi Bayi, daughter of Mahaprabha Amma, and Regent in the period 1924-31) also gave birth to two daughters later in life (in 1923 and 1926).
