According to
Hispanic First Names by
Richard Woods:
Licha: can be from
Alicia,
Elisabeth, Elisea,
Eloisa,
Isabel, or
Leticia.
Quina: from Aquiles (though since Quino is said to be from
Joaquin, I would guess that Quina could also be from Joaquina.)
Chivita: not listed, but Chivete and Chiveto are said to be from
Silvestre.
Chepa: from
Jose (or
Josefa) or
Maria.
Pochencho: not listed, but Pocho is from
Alfonso or
Ambrosio.
Mapy: nothing like it in that book
