Beatrix is a feminine given name, most likely derived from Viatrix, a feminine form of the Late Latin name Viator which meant "voyager, traveller" and later influenced in spelling by association with the Latin word beatus or "blessed". It is pronounced in British English and the same or in North American English. Another North American English pronunciation however approximates that of most other languages: BAY-ə-triks, as shown by US dictionary entries for the former queen of the Netherlands.
