For my own - I say the same thing -
Barbra - spelled as the famous singer / celebrity
Barbra Streisand spells it.
I still (vaguely) long to add
Elizabeth to my name since the occasion that it was erroneously added on legal documents in lieu of my first name. I didn't think much of it at the time - but the name bears so much heritage, and with so many independent nicknames - there is "so much that can be done with the name".
