Names are and should be special. Filled with meaning for you and understandable so that your baby can learn it with easy. The name should be acceptable to a wide cross-section of the Human's you and your baby will come in contact with over the next 40 to 70 years, i.e. some names may make sense in your home, but would be hard to explain to a mother-in-law, etc....
If you choose not to have your baby DNA sexed, it would be wise to select a name that is gender neutral.
With some Amazons, names that are common from the region they are naturally found is a good choice.
I'm not really big into selecting a name until the Amazon has been with us for a least a week or so. Lets just say that Amazon's tend to have big personalities and getting to know them is helpful. Thus a name better fits who they are.
Just my two cents!
