  Notes	Names by which Person may be found in sources Ivo comes Bellomontensis [1] Ivo is Latin for Beaumont and Ivo for Yves, so records for the same person may exist under the name Yves de Beaumont. Ives (I), Comte de Beaumont [2] 990 Birth Year Estimation He birth year is unknown. A popular genealogy on ancestry gives his birth the year 975.[3]. Since his death year is known -- 1059 -- and his earliest appearance in the records is 1022, estimate his age at around 30 when he is called to be a witness and place his birth at, say, 990, with his age at death then being 69. Parents Cawley does not find primary sources giving the parents of Ivo. A popular genealogy makes him the son of an earlier Ivo I (Yves) de Beaumont sur l'Oise [4], born 940 in Beaumont sur l'Oise, and died 1002 in Normandy. That genealogy gives his mother was Gisele Wigeric-Ardennes of Lotharingiam, born 954, daughter of Gilbert Wigeric-Ardennes of Lotharingia, Count of the Ardennes. [4] This information is provided for reference only and is not sufficient to justify creation of a profile for these persons. Background on Beaumont-sur-Oise The county of Beaumont-sur-Oise lay to the north of Paris, south of the county of Beauvais, east of the Vexin and west of the county of Valois, although its precise geographical boundaries are uncertain. Lépinois suggests that the county corresponded to the pagus Camliacensis [le Chambliois] and le pays de Thelle, which together became the ecclesiastical doyenné of Beaumont. The first mention of a count of Beaumont-sur-Oise is dated to 1022, although it is not known when the county was formed. Douet-d’Arcq suggests that it represented a partition of the county of Beauvais, which was granted by Eudes II Comte de Blois to Roger Bishop of Beauvais in exchange for the county of Sancerre in [1013] not long before the appearance of the first comte de Beaumont in the primary sources. Earlier charters dated between 627 and 861 name the pagus Camliacensis, and its main town Chambly, located in the southern part of the future county of Beaumont. Among these charters, “Theudaldus comes” donated property “sitas in pago Camliacense” to the abbey of Saint-Denis by charter dated 799. [2] 1010 Marriage to Emma He married Emma, whose parents are unknown, and who died on 21 July of an unknown year. [2] Emma is named in 1039 donation of a castle quoted below, "cum mea propria conjuge Emma." Casley notes that they had five children and adds that "The Necrologium Bellimontense records the death “XII Kal Aug” of “Emma comitissa”. [2] The Ancestry popular genealogy records that Ivo married Gisele de Chevreuse, born 980 in Beaumont, Normandy. No factual basis for this has been found and she has been delinked. 1022 Witnessed Charter for Abbeyis of Coulombs “Comes Ivo de Bello monte, Ebo miles, Guarinus miles Parisius, Almaricus miles de Monteforte” witnessed the charter dated 1022 under which Robert II King of France confirmed the possessions of the abbey of Coulombs.
