Have seen proof of children named (backwards word in brackets):
Acirema (America)
Adaven (Nevada)
Alucard (Dracula) - this one is not uncommon
Amabala (Alabama) - also may be unrelated to reversed name as it is apparently Zulu meaning "spots" as well
Anozira (Arizona)
Sasnakra (Arkansas)
I know there have definitely been more so will update when I remember!
