St. Adele

St. Adele (also known as Adulla) is a saint from Germany. She became a nun after her husband's death, after making provisions for her son, who became the father of St. Gregory of Utrecht. She founded a convent in Trier in West Germany and became its first abbess, "ruling with holiness, prudence, and compassion". She was a student of St. Boniface; at least one correspondence written to her by him survives. 
She was the sister of St. Imina and the daughter of King Dagobert II of Germany. She died in 730, "after a devout life filled with good works and communion with God". Her feast day is celebrated on 24 December.
