Chronixx was the stage name his friends bestowed on him, replacing the name Little Chronicle he was given as the junior to his father, the artist Chronicle. A little star amongst his peers, he had shown a love for music and song writing from an early age. He was born October 10, 1992 and was named Jamar Rolando McNaughton. His father, a musician, recognised his talents and nurtured him in an environment in which he could grow into whatever area of music he chose. Always accompanying him to the studio, Jamar grew up around the likes of Burro Banton, Norris Man and the legendary Gregory Isaacs.

With a big smile and an engaging personality, he confidently set out to make his mark in music, by writing his first song Rice Grain by the age of five and going on to be choir director and worship leader at 11. Coached by Danny Browne, he recorded his first song with him in 2003. Always displaying his versatility, Jamar, as a young man at St. Catherine High School, harmonised for gospel artistes such as Jermaine Edwards and reggae artiste Lutan Fyah.
