Alwyn Cuthbert Aethelbert
Aethelbert, King of Kent, was the first English King to convert to Christianity. In 597, the Roman Catholic Church approached Aethelbert. The church chose him because he was married to Bertha, a Frankish Christian princess, whose support was essential.
Saint Augustine of Canterbury is credited with converting King Ethelbert.
He had 3 older brothers who all ruled as King before him Aethelbald, Aethelbert and Aethelred.
