Research Notes:

Guillaume de Jumièges records that Rollo captured “Baiocasensem urbem” [Bayeux] along with "nobilissimam puellam...Popam filiam...Berengarii illustris viri" whom he married “more Danico” and by whom he had “Willelmum...filiamque...Gerloc”. Orderic Vitalis records that "xxx annis post cladem Hastingi..., Rollo dux cum valida Danorum juventute" entered “Neustriam”, captured Bayeux (“Baiocas”), killed “Berengarium comitem” and married “Popam...filiam eius”. The Chronico Rotomagensis records that "mortua a Gisla, accepit Rollo propriam uxorem filiam comitis Silvanectensis Widonis". Robert of Torigny combines the information, recording that "Rollo dux Northmannorum" married "Popam prius repudiatam uxorem…filiam…Berengarii comitis Baiocensis neptem vero Widonis comitis Silvanectensis". Another indication of Poppa’s family origin is provided by Guillaume of Jumièges who records that Louis IV King of the West Franks, after the death of the father [Poppa’s son Guillaume I “Longuespée”] of Richard I Comte [de Normandie], marched on Rouen, was received by “Rodulphus et Bernardus atque Anslech totius Normannici ducatus tutores”, and captured Richard, who was taken to Laon but was freed by “Osmundus...consilio cum Yvone patre Willelmi de Belismo” and taken to “Silvanectis” where “Bernardus...comes” [presumably identifiable as Bernard [II] Comte de Senlis [who] was Poppa’s uterine half-brother] protected “nepotem suum Richardum”.

Guillaume of Jumièges records that Rollo married "repudiatam Poppa" again after the death of his wife [Gisela]. ²
