That's really neat. I googled around and the usual spelling is Zenzele (lots of women come up with that name) and it's from the Xhosa language, which I've never even heard of ._. And it seems to be pronounced ZEN-zee-lay or ZEN-zeh-leh. I don't think I'd consider using it unless I had some significant connections to southern
Africa, though, because it is rare and I think it would seem very "foreign" here.
