unusual girls name

Stef

We are so stuck for a girls name, I have spent hours going through posts on here, baby lists online and books etc but nothing is jumping out at us. we like names that are uncommon but it needs to not end in an 'a' sound or have a shortened version ending in an 'e' sound. Also not start with B as surname is a J !! We are all for any wierd and wonderful suggestions. Thanks.
