She was the only child of the couple Francisco Barrecheguren and Concha García, both from wealthy and religious families.

The quality of the teachings transmitted by her father allowed her to receive the Sacrament of Confirmation and the First Communion.

On May 13, 1978, the remains were transferred to the Carmelo di Conchita, in Alhambra and, since November 29, 2007, she has been buried in the Redemptorist Sanctuary of Our Lady of Perpetual Help.

[6] Barreguren's cause was formally opened on 15 April 1946, granting her the title of Servant of God.

[7] A archdiocesan inquiry into her writings and testimonies about her life was completed in 1956 and sent to Rome for examination by the Dicastery for the Causes of Saints.

[2] On May 5, 2020, Pope Francis recognized Conchita's heroic virtues, giving her the title of Venerable.

The celebrant chosen to represent Pope Francis was Cardinal Marcello Semeraro, who inscribed her on the list of Blesseds of the Catholic Church.
