JEAN [III] d'Alençon (-8 Jan 1212, bur Perseigne). A manuscript genealogy of the Lords of Beaumont names "Joannem et Matildam" as the children of "Robertum comitem Alencheii" and his wife "Joanna…filia domini Josberti de Guirchia"[173]. m (1205) as her first husband, ALIX de Roye, daughter of BARTHELEMY de Roye & his wife Petronille de Montfort (-26 Jan 1226). A manuscript genealogy of the Lords of Beaumont records that "Joannem", son of "Robertum comitem Alencheii", married "Aaliz filiam domini Bartholomæi de Roye" but died childless[174]. Philippe II King of France confirmed the marriage contract between "comitem Robertum Alenchonii...Johannis filii" and "Barth. de Roia...Aaliz filiæ" by charter dated 1205[175]. She married secondly (before 1214) Raoul de Nesle Seigneur de Falvy. Her second marriage is confirmed by the necrology of Joyenval which records the death of [her son] "domini Joannis de Nigella filii dominæ Aelidis de Roya" and his donation which was confirmed by his mother[176].
