The Chronica Boemorum names (in order) "Udalricus et Iaromir" as two other sons of "secundus Bolezlaus dux" & his wife, specifying that the former was brought up learning German at the court of Emperor Heinrich II. Thietmar records that "the duke of the Bohemians castrated his brother Jaromir and wanted to suffocate the younger brother in his bath" before sending them both into exile with their mother.
He succeeded after deposing his brother in 1012 as OLDRICH Duke of the Bohemians. He was deposed in 1033. He was restored as joint duke with his brother later in the same year.
The Chronica Boemorum records the death "V Id Nov" of "Oudalricus". The Cronica Principum Regni Boemiæ records the death in 1042 of "Odalricus…filius Boleslai" captured and blinded by "Mezconem Ducem Poloniæ".
The Chronica Boemorum refers to the childless marriage of "Oudalricus", but does not name his wife. 1
