 Connections with Francia went beyond trade and the royal marriages Æthelberht and Eadbald made with Frankish princesses . Eadbald 's granddaughter , Eorcengota , became a nun at Faremoutiers , and his great @-@ granddaughter , Mildrith , was a nun at Chelles . When Edwin was killed in about 632 , Æthelburg , escorted by Paulinus , fled by sea to Eadbald 's court in Kent , but in a further sign of her family 's ties across the channel she sent her children to the court of King Dagobert I of the Franks , to keep them safe from the intrigues of Eadbald and Oswald of Northumbria .
