Josine is a contraction of Josephine
The surname of Miranda
is found among the Spanish, Catalan, Portuguese, Jewish (Sephardic), and Italian people. According to my reference source, it's a "habitation name from any of various places so called. The origin of this frequent placename is uncertain. It seems to be from the Latin word "mirandus" (meaning "wondrous, lovely"), but it is also possible that it is used in the sense of a watch-tower or look-out post" (as derived from the Catalan word "miralla", meaning "watch-tower" or "look-out post").
