text: In addition to Eadbald, it is possible that Æthelberht had another son, Æthelwald. The evidence for this is a papal letter to Justus, archbishop of Canterbury from 619 to 625, that refers to a king named Aduluald, who is apparently different from Audubald, which refers to Eadbald. There is no agreement among modern scholars on how to interpret this: "Aduluald" might be intended as a representation of "Æthelwald", and hence an indication of another king, perhaps a sub-king of west Kent; or it may be merely a scribal error which should be read as referring to Eadbald.
  Liturgical celebration
  Æthelberht was later regarded as a saint for his role in establishing Christianity among the Anglo-Saxons. His feast day was originally 24 February but was changed to 25 February. In the 2004 edition of the Roman Martyrology, he is listed under his date of death, 24 February, with the citation: 'King of Kent, converted by St Augustine, bishop, the first leader of the English people to do so'. The Roman Catholic Archdiocese of Southwark, which contains Kent, commemorates him on 25 February.
  He is also venerated in the Eastern Orthodox Church as Saint Ethelbert, king of Kent, his day commemorated on 25 February.
