Master P was born Percy Robert Miller on April 29, 1970 in New Orleans, Louisiana. Miller's early life was quickly disrupted by divorce, so he was raised by a single father and experienced poverty alongside four siblings. He lived in the Calliope Projects throughout his childhood. Memories of the challenges he faced in the projects eventually became catalysts for his artistic success.
When he was 19, Miller married Sonya C and had nine children with her: Lil Romeo, Cymphonique, Tytyana, Italy, Veno, Young V, Hercy, Mercy and Inty. Lil Romeo, Cymphonique and Veno have worked in the entertainment industry.
