I like it. It's pretty and soft. I guess I don't think that it's close to
Anna or
Hannah, since I like
Savannah and am neutral on
Anna and dislike
Hannah. I wouldn't use it because of the city of
Savannah GA. I've been to the city and I like the city (though the heat and humidity are awful in the summer) but using
Savannah would seem to me to be declaring my Southern allegiance or something and I'm not Southern. Even though I know many non-Southerners must use the name, that's still what it would feel like to me. But I like it on someone else's child.
According to the statistics, it's popular, though I've never known one or anybody who named their child
Savannah, but still, if one wants to avoid a popular name, you have to trust the statistics.
I prefer
Savannah. I always like the H at the end of a name when it's an option, just makes the name look prettier and more feminine.
