"In a dual ceremony on 5 August Germanus ... and Maurice were elevated to the rank of Caesar and betrothed to Tiberius' two daughters, Charito and Constantina.
[2] This narrative is somewhat contradicted by the Historia Francorum of Gregory of Tours, which also records Byzantine events.
He depicts Maurice as hand-picked to be heir, first by dowager empress Sophia and then by Tiberius II, but this account is doubted by Whitby.
[3] According to a statement in Jordanes' Getica, the senior Germanus was a descendant of the noble Roman clan of the Anicii.
A number of historians identify him with the patricius Germanus mentioned in the 7th century, whose daughter married Maurice's eldest son Theodosius,[6][7][8] though the identification is not conclusive.
