The last name "Canjura" seems to only be found in Central America. 
One person I queried said that it could be a Mayan term for "Seven
Monkeys" or the Moorish "Al-Khanjur", but another acquiantance in
Spain said it could *not* be found in the Madrid phone book (ie, it is
probably not Moorish).  There is an herb called "Canjura" in Panama
that is used for leprosy.  However, that's quite a bit a ways from
Honduras and El Salvador, the two nations that have Canjuras in them. 
So, what IS the origin of the name Canjura?
