Hyla suggested : I'd try looking by spelling it Bridgid
Good thinking and I did find a link for more than you ever wanted to know about Saint Brigid, the Irish saint ....
http://www.cin.org/saints/bridget.html
and from what it says it would be a lovely name for your baby girl.
However still no help with the original Brigid/Bridget the Celtic godess who is characterized as mythical by above site. HA!
Anyone offer other help?
All I've gotten is "no match found." sigh
wow
