The Vita Arnulfi names "Emmonem et Ottonem fratrem eius" as sons of Liutgarde, daughter of Albert [I] Comte de Namur. From a chronological point of view, it is not possible for Emmo and his brother to have been the children of Otto de Looz who...is recorded in another source as the husband of Liutgarde de Namur. No primary source has been identified which confirms that Emmo and Otto were the sons of Comte Giselbert, although this suggested parentage would fit the chronology of the family.
“...Ottonis advocati et fratris eius Emmonis comitis de Los, Alberti comitis de Musal...” signed the charter dated 1059 under which “Fredericus...Lothariencium dux” donated a serf to Saint-Trond.
The necrology of Liège Saint-Lambert records the death "XVII Kal Feb" of "Emononis comitis". 1
