Alexius

Alexius is the Latinized form of the given name Alexios (Greek:Αλέξιος, polytonic Ἀλέξιος, "defender", cf. Alexander), especially common in the later Byzantine Empire. Variants include Alexis with the Russian Aleksey and its Ukrainian counterpart Oleksa/Oleksiy deriving from this form. The female form is Alexia (Greek:Αλεξία) and its variants such as Alessia (which male form is Alessio) in Italian.
