Naming information
Name origin: Greek.
Mythology: Baukis and Philemon were a poor elderly couple who were blessed by Zeus and Hermes after showing them hospitality while disguised as peasants. Richer folk in the town had turned the gods away. In consequence, Zeus flooded the rest of the town and turned the simple cottage into an ornate temple. The couple’s wish to be guardians of the temple was granted, as was their wish to die together. On that day, they were changed into an intertwining pair of trees, an oak and a linden.

Summary and references
Mark Andrew Holmes associates Baucis with “generosity, hospitality, or devotion”[1]. I’d add maturity, prudence, parental care, standing apart, and possibly carving out one’s own fate.
