  Research Notes:

The Nobiliario of Pedro Conde de Barcelos names "D. Alonso Sanchez, El Infante D. Pedro, El Infante D. Fernando Conde de Flandes, El Infante D. Enrique" as the sons of "D. Sancho Rey de Portugal" and his wife "D. Aldonça". The Chronicon Conimbricensi records the birth “IX Kal Apr” in 1188 of “Rex Fernandus filius Regis Sancii et Reginæ Dñæ Dulciæ”. The De Rebus Hispaniæ of Rodericus Ximenes names "Ferdinandum" as another son of "Rex…Sancius". “Sancius...Portugalensium Rex et uxor mea Dona Dulcia...cum filiis nostris Rege Domno Aldphonso et Rege Domno Petro et Rege Domno Fernando et filiabus nostris Regina Dona Therasia et Regina Domna Sancia” donated “paludem de Otta” to Alcobaça monastery by charter dated Mar “Era 1228” [1189 or 1190 if O.S.]. The testament of “Sancius...Portugaliæ Rex”, dated Oct 1209, bequeathed property to “filius meus Infans Donnus Petrus...Infans Donnus Fernandus...” The Genealogica Comitum Flandriæ Bertiniana names "fratrem regis de Portigal, nomine Fernandum" husband of "Iohanna".

He succeeded as FERRAND Count of Flanders and Hainaut in 1212, by right of his wife. Although the protégé of Philippe II King of France, he exiled several prominent Francophiles after arriving in Flanders and opened negotiations with England. He refused to participate in King Philippe's projected invasion of England in 1213. The French army devastated Flanders in revenge, forcing Count Ferrand briefly to seek refuge in Zeeland. He was captured at the battle of Bouvines 27 Jul 1214, and taken to Paris where he remained a prisoner. He returned to Flanders in 1227 after payment of the ransom under the Treaty of Melun. He founded the convent of Marquette near Lille.

The Continuatio Clarimariscensis records the death "1233 6 Kal Aug" of "Fernandus Flandriæ comes". The Annales Blandinienses record the death in 1233 of "Ferrandus comes Flandrie et Haynonie" and his burial at "Merketo". The Chronica Andrensis records the death in 1233 "apud Noviomum" of "comes Flandrie Fernandus" and his burial "iuxta Insulam". The Chronicle of Alberic de Trois-Fontaines records the death in 1233 of "Fernandus comes Flandrie" and his burial "in abbatia delle Marckete". 1
