Missionary Sisters of the Holy Rosary (MSHR) is a Roman Catholic apostolic congregation of women religious founded by Bishop Joseph Shanahan CSSp (Irish born bishop in Nigeria) on 7 March 1924, in Killeshandra, County Cavan, Ireland.[1] They are sometimes referred to as the Killeshandra Nuns.[2] The order received canonical recognition by Pope John XXIII in 1938.?[3] Its initial mission was to Nigeria in 1928, but over the years it grew to mission in other countries in Africa, developing schools and medical facilities.
