Don't go with anything that rhymes with "maiden," they are going to be seen everywhere in kindergartens in five years.
There are a lot of classic names that are not overused that also have a Spanish version. If your husband is Spanish, why not go for it with something that is Spanish? A friend of mine is Korean and her husband is German, and they named their son Deiter. It's really cute on him!
There's a good book written for writers (so you might find it in the reference section) called the Character Naming Sourcebook. It has all the names by the countries, and since it's not a baby-names book it has a lot of more unusual names (but not unusual because they are cutesied up with fake spellings or invented. They're real names.) Maybe you could locate it at the library or a bookstore.
Here's a good example, Tristan is the same in Spanish and English, it is not seen every day, it is distinguished, it is not fussed up with fake "creative" spelling, and although it is not all that common people can understand it and pronounce it correctly with one reading. If you get a list of Spanish first names, you should be able to find at least five or six that are the same way.
