His parentage is recorded by Orderic Vitalis, who specifies that he was the twin of his brother Robert[3098]. He succeeded his father as Comte de Meulan, and to his fiefs in Normandy. He and his twin brother were brought up at the court of Henry I King of England[3099]. He rebelled against King Henry, with his brothers-in-law Hugues de Montfort, Hugues de Châteauneuf and Guillaume Louvel[3100], but was captured at the siege of Vatteville 26 Mar 1124. The king confiscated his lands and held him in prison for five years, successively at Rouen, Bridgenorth and Wallingford, until 1129. After the accession of King Stephen in 1135, Waléran supported the king who created him Earl of Worcester in 1138. However, he fled at the battle of Lincoln 2 Feb 1141 and came to an agreement with Geoffroy Comte d'Anjou who gave him the castle of Montfort-sur-Risle. "Gualeran comes Mellensis" confirmed his foundation of a chapel "at Watteville before the gates of his castle" by charter dated [1154/55], witnessed by his sons Robert and Gualeran and his wife Agnes[3101]. Robert of Torigny records that "Gualerannus comes Mellenti" became "monachus Pratelli" in 1166[3102].

Daughter of King Stephen, Orderic Vitalis records her betrothal when she was "two years old" but does not name her[3103]. The Chronicon Valassense names "comes Mellenti Gualerannus" and "uxore sua regis Stephani familia"[3104]. William of Newburgh records her burial, together with that of her brother Baudouin, as "children of King Stephen and Queen" and wife of "comitis de Medlint", quoting the records of Holy Trinity[3105].

"G comes Mellenti et A comitissa uxor mea" donated property to Notre-Dame de la Trappe by undated charter[3107]. Her brother gave her Gournay-sur-Marne as her marriage portion[3108].

Gual. domini mei…et Roberti filii mei" by undated charter[3109].
