I'm sorry, I don't remember the name of the husband but Memory Beta may well have the information, I'll go look it up.
As for genders, Starfleet Command listed the Hydrans as having three sexes but not only were they not shown, the mention itself was brief and games are not all that canon to begin with.
The Andorian sexuality is one of the most interesting in Trek. They have Four sexes, each take part equally in the courting, relationship, sexual intercourse and even marriage. The four split into two "male" and two "female";, with only the male and female most resembling Human genders leaving their homeworld apparently, the two stranger sexes remain on Andor. This can lead to trouble maintaining a good population density, achieving a balanced and stable union of four rather than two.
