Research Notes:
Her name, the fact that she was the wife of Gorm and the mother of Harald, and that she died before Gorm, are are well documented facts from the contemporary Jelling runestones quoted in my three part Gorm posting on the 5th of this month. Thus, the main question is her parentage. There are two main claims:
Saxo (Book 9) makes her a daughter of Aethelred of England (d. 871).
Various Icelandic sources (Heimskringla, Jomsviking saga, etc.) make her a son of Klakk-Haraldr or Harald Klak, a king in Jutland. Later sources identify him with the Danish king Harald who begins to appear in the Frankish annals in the year 812.
The chronological problems with both of these claims are evident. Although one might be able to concoct birthdates for Thyre and her son Harald that are within the realm of possibility for either of these two scenarios, such dates would still give an improbably long chronology, and both accounts must be considered unlikely. Although it is possible that either one of the above accounts might contain some garbled version of the truth, it is not possible to discern what that truth might be without further evidence, and Thyre's parentage must be regarded as unknown.
