NDBS meaning in General ?

Our Lady of Prompt Succor (French: Notre Dame du Prompt Secours) is a Roman Catholic title of the Blessed Virgin Mary associated with a wooden devotional image of the Madonna and Child enshrined in New Orleans, Louisiana, United States of America. The image is closely associated with Mother Saint Michel, the Superior of the New Orleans Ursulines.

Pope Pius IX authorised the public devotion to the Marian title on 21 September 1851 and designated the 8th of January as its feast day of thanksgiving. Pope Leo XIII granted a Canonical Coronation to the image through Archbishop Francis Janssens on 10 November 1895.

The image is also known by its connection to President Andrew Jackson who was present before the image during and after the Battle of New Orleans against the British invasion. Under this Marian title, the Virgin Mary is designated as the Principal Patroness of Louisiana and the Archdiocese of New Orleans dating from a 1928 Papal bull from the Sacred Congregation of Rites. The image is presently enshrined at the National Shrine of Our Lady of Prompt Succor while her feast day is celebrated on 8 January.
