Alexia González-Barros y González was born on March 7, 1971, in Madrid, Spain, into a devout Catholic family deeply involved with the Opus Dei movement. She was the youngest of seven siblings and was raised in an environment filled with faith, freedom, and joy. From an early age, Alexia exhibited a profound piety and a strong devotion to her guardian angel, whom she affectionately named "Hugo." She received her early education at the "Jesús Maestro" school in Madrid, run by the Company of Saint Teresa of Jesus. At the age of eight, she made her First Communion in Rome, near the tomb of St. Josemaría Escrivá, the founder of Opus Dei. The following day, she received a blessing from Pope John Paul II during a general audience.

In December 1984, at the age of 13, Alexia began experiencing pain in her back and arm, leading to the diagnosis of a malignant tumor in her vertebral column, which eventually caused paralysis. Despite enduring four operations and ten months of intense suffering, she maintained an unwavering faith and offered her pain for the Church and the Pope. Her prayerful acceptance of her condition was encapsulated in her words: "Jesus, I want to get better, I want to be healed; but if you don't want that, I want what you want." ‍

Alexia passed away on December 5, 1985, in Pamplona, Spain. Her exemplary faith and virtue led to the initiation of her cause for canonization. On July 5, 2018, Pope Francis recognized her heroic virtues, declaring her Venerable.
