The Annales Egmundani name "Othelhildis comitissa" as wife of "Theodericus comes septimus [Hollandensium]" but do not give her origin. The Chronologia Johannes de Beke records the marriage of Count Dirk V and "Otihildim filiam prepotentis ducis Saxonie". The name "Othelindis" suggests a Saxon origin.... However, it is unlikely that Othelindis's father was duke of Saxony, because of the consanguinity that would have resulted between the parties no reference to which has been found in the sources so far consulted. No indication has been found of her precise Saxon origin. "Theodericus…Holtlandensis comes…Florentii filius" recites the ownership history of properties claimed by the church of Utrecht in Holland, by spurious charter dated 26 Jul 1083, probably written in [1130], which names "Othelhilda uxore mea".
The Chronologia Johannes de Beke records the death "XIV Kal Dec" of "Uthilhildis" wife of Count Dirk V and her burial at Egmond. Beke's Egmondsch Necrologium records the death "XIV Kal Dec" of "Othilhildis comitissa" and her burial at Egmond with her husband. 1
