Joylette Hylick was born into a household driven by numbers and resilience. Her father, James Goble, was a chemistry teacher who died of an inoperable brain tumor in 1956, leaving Katherine a widow with three young daughters: Joylette, Constance, and Katherine. The family lived in the East End of Newport News, Virginia. Segregated public facilities were the daily standard, but the Goble household operated under a strict standard of intellectual discipline. Schoolwork took precedence over recreation. Dinner conversations frequently centered on equations and grammar.

When Katherine joined the West Area Computing unit at the National Advisory Committee for Aeronautics (NACA), the precursor to NASA, in 1953, her daughters knew only that their mother did "important math" across town at Langley Research Center. Katherine remarried in 1959 to artillery officer James A. Johnson, who became a steady co-parent as spaceflight projects consumed Langley's engineering corps. Hylick recalled that her mother never discussed racial slights or institutional glass ceilings at the dinner table. Katherine simply demanded excellence, expecting her daughters to master algebra before entering high school.

That domestic culture shaped Hylick's trajectory. She attended Hampton Institute (now Hampton University), the historic HBCU where her mother had deep ties. Hylick chose mathematics as her major. It was not an act of imitation; it was the native language of her childhood home.
