[Opinions] It's positively beautiful
It book looks and sounds stunning. Unfortunately, not many Americans will have ever seen any name like it. I don't think it will cause many problems, though. It's quite phonetic and doesn't have any obscure pronunciations that will flabbergast the common American. Plus, so many Americans take standard English names (like Caitlin) and turn them into atrocities (like Kheightlynne) that Sanziana might even be simple for them to figure out! Plus, it comes with great nicknames such as Sanzi, Zia (I knew a girl named Zia-Zan once) and Ana. I'd say go for it. It's beautiful. Congratulations on your daughter!
