St Mariam Sultaneh Danil Ghattas (4 October 1843-25 March 1927), was a Dominican tertiary.  She first joined the Sisters of Joseph but following a vision of the Blessed Virgin Mary she received in Bethlehem, she co-founded the Rosary Sisters (Sisters of the Holy Rosary of Jerusalem of the Latins; Congregation of the Sisters of the Most Holy Rosary of Jerusalem). The visions were kept a secret for 53 years, and her journals read only post mortem. People recognized the virtues of humility and meekness in Mother Mariam, similar to those of the Mother of God.

Ghattas promoted the Confraternity of the Immaculate Conception (later known as, “Daughters of Mary”) and also the Confraternity of the Christian Mothers.

Mother Mariam spent her life working for the poor and the education of Palestinian Christians, and her Sisters continue that work today.

St Mariam Sultaneh Danil Ghattas was beatified on 22 November 2009, in the Basilica of the Annunciation, Nazareth; she was the second Palestinian nun to be beatified. She was canonized by Pope Francis on 17 May 2017.
