Beatrix f
English and German: from a Late Latin personal name, which was borne by a saint executed in Rome, together with Faustinus and Simplicius, in the early 4th century. The original form of the name seems to have been Viātrix, a feminine version of Viātōr ‘voyager (through life)’, which was common among early Christians. This was then altered by association with Latin Beātus ‘blessed’ (Via- and Bea- being pronounced very similarly in Late Latin).
