Life Rafaela Ybarra Arambarri de Vilallonga was born in Bilbao on 16 January 1843 to affluent parents part of the upper-class. Her baptism was celebrated in her local parish church on 17 January and she was baptized in the name of "Rafaela María de la Luz Estefanía de Ybarra i Arambarri. Her parents were Gabriel Ybarra y Gutiérrez de Caviedes and María del Rosario de Arambarri y Mancebo.

Her Confirmation came on 22 May 1844 and she made her First Communion on 21 May 1854. Arambarri married José de Vilallonga y Gipuló (b. 1823) on 14 September 1861. An apostolic process was then held in the Diocese of Bilbao from 1954 until 1957 while both processes received the validation of the Congregation for Rites in Rome on 16 June 1959.

An antepreparatory committee met to discuss and approve the cause on 19 May 1964 as did a preparatory committee on 15 April 1969 and soon after a general one on 12 June 1969. Pope Paul VI named Vilallonga as Venerable on 16 March 1970 after he confirmed that the late widow had led a model Christian life of heroic virtue. The process for investigating a miracle took place in Buenos Aires in Argentina after Cardinal Santiago Copello inaugurated the process in 1955 and then closed it later in 1957; the Congregation for the Causes of Saints validated the process on 15 March 1974 before a medical board approved it on 16 July 1975. Theologians approved it sometime later on 12 July 1983 as did the C.C.S. on 13 September 1983; Pope John Paul II granted definitive approval that the healing was a miracle and then beatified Vilallonga on 30 September 1984 in Saint Peter's Square.

The process for the miracle needed for sainthood spanned from 26 July 2004 until 7 December 2004 and received C.C.S. validation on 10 June 2005. A medical board approved this miracle on 26 November 2009.

The current postulator for this cause is Dr. Silvia Mónica Correale.
