Henry I was the Count of Louvain from 1015 until 1038.
Henry was a child of Count Lambert I of Louvain and his wife, Gerberga, daughter of Duke Charles of Lower Lorraine.
He was assassinated in 1038 by a knight named Hermann who was his prisoner[citation needed].
Without a male heir, he was succeeded by his brother, Lambert II Henry's wife, whose name is not recorded in history, gave birth to Otto,[1] who succeeded Henry in 1038.
A 19th century genealogy, Genealogica ex Stirpe Sancti Arnulfi descendentium Mettensis[2] also attributes three daughters to Henri (Adelaide, Cunegonde and Adele), but it seems that they were daughters of another Henry, descendant of the counts of Louvain, who lived around 1100.
