Input: Question: How many members were on the low court when they met in Pieterlen? Passage 1:The Vorem Holz 3 archeological site contains the remains of a Bronze Age settlement in the Pieterlen municipality. A first- to third-century Roman estate has also been discovered. During the Middle Ages there were several settlements in the modern municipal borders. A medieval bath house was found at Thürliweg. The early medieval Totenweg cemetery served two different settlements during the 7th-8th centuries. A medieval fortification at Gräuschenhubel has also been discovered. During the Late Middle Ages the village was mentioned as the personal property of the Lords of Pieterlan. By the end of the 13th century, the village passed through the hands of a number of nobles before ending up under the Prince-Bishop of Basel. Under the Prince-Bishops the village was combined with Romont, Reiben (now part of Büren an der Aare and Meinisberg) to form the southern-most ecclesiastical district of the Erguel seigniory. The low court met in Pieterlen while the high court was in Reiben and was held on the bridge over the Aare river. Militarily it was part of the banner of Biel.
 Passage 2:He changed his surname to Percy when he married Lady Elizabeth Seymour (1716–1776), daughter of His Grace The 7th Duke of Somerset, on 16 July 1740, through a private Act of Parliament. She was Baroness Percy in her own right, and indirect heiress of the Percy family, which was one of the leading landowning families of England and had previously held the Earldom of Northumberland for several centuries. The title Earl of Northumberland passed by special remainder to Hugh Percy, as Elizabeth's husband, when her father died on 7 February 1750; he had been created 1st Earl of Northumberland in 1749. In 1766, the earl was created 1st Duke of Northumberland and was created Baron Lovaine on 28 June 1784, with a special remainder in favour of his younger son, Algernon. (The Louvain family of the Landgraviate of Brabant, which married the Percy heiress, was the origin of the Percy family of England). Richard de Percy, 5th Baron Percy (c. 1170–1244) (who adopted the surname Percy), was the son of Joscelin of Louvain (1121–1180), styled "brother of the queen" (referring to Adeliza of Louvain, second wife of King Henry I of England, by his wife Agnes de Perci, suo jure Baroness Percy, the heiress of the Percy estates in England.) He was created a Knight of the Order of the Garter in 1756 and a Privy Counsellor in 1762.
