O Mary of Graces

O Mary of Graces is a traditionally Catholic Marian hymn based on an ancient Irish prayer to Mary, the mother of Jesus. Two versions of the hymn exist based on differing translations made of the original prayer by Priest Douglas Hyde and J. Rafferty, with the Hyde version being more popular.

In modern history, the hymn has been present in a number of hymnals, weddings, and music performances by Catholic schools. Covers of the hymn have also been made by religious sister congregations including the Daughters of Mary, Mother of Our Savior and the Sisters of the Holy Humility of Mary.

Translation
The hymn originates from an ancient Irish prayer to Mary, the mother of Jesus. It was later translated into English and turned into a hymn by the Priest Douglas Hyde (1860–1949), and another man named J. Rafferty. The differing translations of the prayer became two versions of the hymn, which despite a difference in translation and melody patterns, hold very similar rhythms.

Below, the two versions of the hymn are displayed. Both versions are formatted the same way the Hyde version was displayed in the May 1914 newspaper segment from The Catholic Columbian as to aid in comparison.

The Hyde version of the hymn is sometimes performed with variations, including a variation with an additional three verses added onto the end not present in the Rafferty version.

Modern usage
In modern history, the hymn is used traditionally in Catholic settings. The Hyde version of the hymn specifically, which is more commonplace than its counterpart, has been used in at least three hymnals, and was the version used in a cover of the hymn by the Catholic religious sisters congregation, the Daughters of Mary, Mother of Our Savior, for their likewise-named 1998 album "Mary of Graces".

Other instances of the Hyde and other, unclear, versions of the hymn have been performed for music recitals at the Southwestern Louisiana Institute, by the glee club at Mount Saint Joseph Academy in New York, by the glee club at St. Mary's Star of the Sea School in Pennsylvania, for a record by the Sisters of the Holy Humility of Mary in Pennsylvania, by the glee club at Columbus Catholic High School in Wisconsin, for a music festival by St. Mary's School of Neillsville in Wisconsin, and at a number of Catholic weddings. A unique version of the hymn beginning with an oboe solo was also created by composer William Ferris Chorale in 2007.

The hymn has been performed by choirs, duets, and orchestras, which are sometimes accompanied instruments, including: guitars, harps, organs, synthesizers, oboes, and/or violins. The hymn is uncommonly performed using the traditional Gaelic language, but sung in the same rhythm as one of the two modern versions.
