The Annalista Saxo records that "Eila" daughter of "Lotharius comes senior de Walbike" married "Bertoldus comes", their son being named Heinrich. She built the Münster at Schweinfurt. During her son's rebellion in 1003, she secured favourable treatment during the siege of her castle by threatening to take refuge inside the church and let herself be burned alive there.
The death of "Eila filia Lotarii de Waldbike, mater Heinrici marchionis" is recorded in the Annalista Saxo on "XIV Kal Sep", which specifies that she was buried in Kloster Schweinfurt which she had founded. Thietmar records the death of "Countess Eila" on 19 Aug and her burial in the monastery which she had constructed. 1
