2. Early life and background
Isabela Merced's formative years were shaped by her bicultural identity and early exposure to the performing arts, which eventually led her to pursue a career in entertainment.
2.1. Childhood and education
Isabela Merced was born in Cleveland, Ohio, United States. Her mother, Katherine, was born in Lima, Peru, while her father, Patrick Moner, was born in Louisiana. Merced has stated that her first language was Spanish, and she encountered difficulties with English when she first began grade school. She considers herself more Peruvian than American, reflecting her strong connection to her mother's heritage. She also has two brothers. Demonstrating her early academic aptitude, Merced was accepted into college at the age of 15.
2.2. Beginnings in acting
Merced's acting journey began under unusual circumstances after her family's Cleveland home was destroyed by a fire. As a fan of Judy Garland, her parents encouraged her to audition for a local production of The Wizard of Oz as a distraction from their loss. She successfully auditioned and was cast as a Munchkin. Her talent was further nurtured at the Fairmount Performing Arts Conservatory, led by Broadway producer Fred Sternfeld. Sternfeld recognized Merced's potential and advised her mother to take her to New York City to audition. Initially hesitant, her mother agreed, and the family moved to New York City for a month to support Merced's aspirations on Broadway. It was during this period that she secured her first professional acting job, a Claritin commercial, on what was intended to be her last day in the city. Merced's early inspirations included films featuring Shirley Temple and Judy Garland, and she began performing in local community theater at the age of six. She made her Broadway debut at age ten in a production of Evita, where she performed a song in Spanish alongside Ricky Martin.
