you could have her middle name be named after a scottish (celtic) goddess...
i don't know your surname so it may not fit, but how does...
Breagha Anu sound? (anu is like mother earth, warm and inviting, goddess of plenty)
or
Breagha Cerridwen (cerridwen is the goddess of nature and the moon)
or
Breagha Morgay (morgay is a harvest goddess from the scottish/english border)
or
Breagha Nimue (nimue is a celtic moon goddess and also found in the king arthur mythology)
