Research Notes:

The question of Philippa´s birth date has been studied by Bert M. Kamp who concluded that she was born "about 1314"... The History of Henricus Dapifer de Diessenhoven records that "dominus Ludewicus et rex Anglie et marchio Iuliacensis" had married "tres…sorores…fillies comitis Hannonie sive Hollandie". Froissart records the marriage in "1327" [presumably O.S.] of "li jones rois Edouwars" and "Phelippe de Hainnau" in "l´eglise cathedral, que on dist de Saint Guillaume", adding that the king was 17 years old and "la joine roine sus le point de quatorze ans". Assuming that the last passage should be interpreted as meaning that Philippa was nearly, but not yet, 14 years old, it would place her birth in late January or early February 1314. However, the text may not be totally reliable as King Edward would only have been 16 years old at the time of the marriage if his birth is correctly stated as 13 Nov 1312... The papal dispensation for the marriage between “Edvardo regi Angliæ” and “Philippæ natæ...Guillielmi comitis Hanoniæ” is dated 30 Aug 1327.

The Chronicon Angliæ records the death “in dia Assumptionis Beatæ Mariæ” of “domina Philippa regina Angliæ” and her burial “apud Westmonasterium”, dated to 1369 from the context. ²
