According to forebears.io, there are 369 people who bear this name, and 338 of them are in India. Only 3 are in Brazil. It is given as a feminine name roughly 60% of the time.
I live in Tucson, Arizona. I saw the word "SARAVA" on a personalized license plate and I looked it up. (No, I was not driving.) And I learned something new. If it ever catches on as a person's name, at least I'll know what it means.
I am Brazilian and absolutely NO ONE in Brazil is named this. It sounds extremely tacky, and real people who follow Candomblé would probably find it kind of weird as a person's name. It doesn't even sound like a masculine name; if anything, it sounds really girly.
