Based on this from Wikipedia, citing an external source, it appears to be Brigid.
Cormac's Glossary, written by Christian scribes in the 9th century and based on earlier sources, says that Brigit was a goddess and daughter of the Dagda. It describes her as a "goddess of poets" and "woman of wisdom" or sage, who is also famous for her "protecting care". It says that Brigit has two sisters: Brigit the physician or "woman of healing", and Brigit the smith. It explains that from these, all goddesses in Ireland are called Brigit; suggesting that it "may have been more of a title than a personal name".

Just a guess but maybe the name changes over the centuries.
