Who married Henry IV, Count of Luxembourg?

Henry the Blind (c. 1113 – 14 August 1196; French Henri l'Aveugle, Dutch Hendrik de Blinde), sometimes called Henry IV of Luxembourg, was his father's heir as Count of Namur from 1139 until his abdication in 1189, and heir of his mother's family as Count of Luxembourg from 1136 until his death. He also inherited the smaller lordships of Longwy, La Roche-en-Ardenne and Durbuy.

Henry is an important figure in the history of the southern Netherlands and the modern countries of Belgium and Luxembourg. He is especially important to the history of the county of Namur, where he was the last member of the first line of counts, and the most powerful of them. His important inheritances were divided again after his death, bringing Namur and Luxembourg to different families. His daughter, who was born when he was old, kept Luxembourg and the smaller Ardennes lordships, while descendants of his sister Alice, who were also counts of Flanders and Hainaut, added possession of Namur to their dominion.

Henry lost the use of his eyes in 1182, but was not referred to as "the blind" until much later. Modern historians use that byname in order to distinguish him from a later count, Henry I, Count of Vianden.

Laureta of Laurentia van Vlaanderen (1113–1175, mogelijk 1198) was een dochter van de Vlaamse graaf Diederik van de Elzas en Swanhilde. Zij is viermaal getrouwd geweest:

1. 1139–1145: getrouwd met Iwein van Aalst. Ze kregen een zoon: Diederik van Aalst. Het huwelijk eindigde door de moord op Iwein.
2. 1150–1152: getrouwd met Hendrik II van Limburg, diens tweede huwelijk. Dit huwelijk bleef kinderloos en werd na twee jaar ontbonden.
3. 1153: getrouwd met Rudolf I van Vermandois. Ze kregen een dochter, Eleonora van Vermandois.
4. 1159–1163: getrouwd met Hendrik I van Namen. Dit huwelijk eindigde door een scheiding. Laureta werd non in de Abdij van Vorst hoewel ze vanwege de scheiding werd geëxcommuniceerd door de bisschop van Kamerijk.
