Minmini was born on 12 August 1970, as the fourth daughter of P. A. Joseph and Treeza. Minmini was known as P. J. Rosily in school. She was also fondly called Mini. Her father, P. A. Joseph, was crazy about art and artistes. Starting her career at the age of 5 with the Kalabhavan orchestra, she became a professional singer at 10. Treeza was a singer, though not a professional. Mini's elder sisters sang in the choir in their village church. Emulating them, Mini also began to sing. Her father taught her to sing in rhythm and pitch. The sisters participated in competitions while they were studying in St Francis Girl's High School, Aluva. One of the sisters, Jancy, sang in Kalabhavan's ganamela troupe.
She won numerous prizes in singing competitions right from her childhood, including the first prize in light music in the 1986 state youth festival and the 1987 university youth festival. She had become a regular singer at Cochin Arts and Communication (CAC) by then. After pre-degree, Mini decided to study music. She was admitted to RLV Music Academy in Thrippunithura. However, she could not concentrate on studies as she had many stage programmes and recordings.
