The first thing that comes to my head when I hear Etta is the famous singer Etta James. Other than the fact that Etta is an underappreciated and underrated name, it is a very sweet name that should have a higher ranking in terms of popularity.
I hate all names ending in -etta, they all sound like names of unintelligent country girls from several decades back. This is just a minimalist variation of all those hideous names.
