The primary source which confirms her first marriage has not yet been identified, although she is named “dominam Johannam de la Marcha matrem meam” in the testament of her daughter Isabelle.... Her birth date is estimated in light of the birth dates of her older siblings ... and because she was recorded in her first husband’s testament in Dec 1280 as having two children. She and her sister Isabelle, as joint heiresses of the counties of la Marche and Angoulême, agreed in May 1309 their transfer to Philippe IV "le Bel" King of France, when their territories were united into the royal domain. Philippe IV King of France granted "castra…de Choec et de Payrac" to "Johanne de Marchia, sorori germane Guidonis quondam comitis Marchie et Engolisme", by reason of the rights she had “in successione dicti Guidonis necnon Guidonis de Marchia patrui ipsius Johanne”, by charter dated Aug 1310.
The Chronicle of Tintern Abbey, Monmouthshire records that "Petro de Genyvile" married "Johannam filiam --- comitis Marchiæ". 2
