Name: Oda (Ode) de Conteville: Pedigree Resource File: Birth: About 0990, Conteville, Eure, Normandy, France; Death: After 1014, France; Marriage: Before 1015, France; Father: John (Jean) de Burgo de Conteville, Vicomte de Comyn**; Mother: Mrs-Jean de Conteville**; Spouse: Waleran III, Count de Meulan**; Children: Adeliza (Adeline) de Meulent, Countess of Meulen**, Marie de Meulan**
↑ Note: Unfortunately, Oda de Conteville's alleged father, John de Bourg/Jean (Conteville) de Burgo, is said to be fictitious:
"This 10th-century Jean de Conteville is fictitious, as is the Blois line to him in the first of your links.
"Nothing is known of the family background of Waleran's first wife, Oda. All we known of her for certain is that she was mother of five children by 1024 and after her husband unsuccessfully tried to get their marriage annulled she died as a nun at Notre-Dame de Coulombs by 1033.
"You can safely disregard any internet genealogy that includes her as a sister of Herluin of Conteville, or that traces the lineage of a Jean of Conteville through imaginary Baldwins of Blois."
