Please answer the following question: Information: - Henry II of Brabant ( French : Henri II de Brabant , Dutch : Hendrik II van Brabant , 1207 -- February 1 , 1248 ) was Duke of Brabant and Lothier after the death of his father Henry I in 1235 . His mother was Mathilde of Flanders Henry II supported his sister Mathilde 's son , William II , Count of Holland , in the latter 's bid for election as German King . - The House of Reginar (later known as the House of Brabant) was a kin-group in Lotharingia during the Carolingian and Ottonian centuries. They were the first dynasty of the County of Hainault and they supplied two Dukes of Lorraine and the Landgraves and later Dukes of Brabant, Dukes of Lothier and Dukes of Limburg. The main branch extinguished in 1355, leaving its duchies to the House of Luxembourg which in turn left them to the House of Valois-Burgundy in 1383. A side branch is the House of Hesse which ruled Hesse from 1264 until 1918 and is still existing today. - The Duke of Brabant was formally the ruler of the Duchy of Brabant since 1183/1184. The title was created by the German Emperor Frederick Barbarossa in favor of Henry I of the House of Reginar, son of Godfrey III of Leuven (who was Duke of Lower Lotharingia at that time). The Duchy of Brabant was a feudal elevation of the since 1085/1086 existing title of Landgrave of Brabant. This was an Imperial fief which was assigned to Count Henry III of Leuven shortly after the death of the preceding Count of Brabant, Count Palatine Herman II of Lotharingia (born 20 September 1085). Although the corresponding county was quite small (limited to the territory between the rivers Senne and Dender) its name was applied to the entire country under control of the Dukes from the 13th century on. In 1190, after the death of Godfrey III, Henry I also became Duke of Lotharingia. Formerly Lower Lotharingia, this title was now practically without territorial authority, but was borne by the later Dukes of Brabant as an honorific title. Given the paragraphs above, decide what entity has the relation 'noble family' with 'house of reginar'.
