Input: Consider Input: Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.
