Lilias

Lilias Folan is a famous yoga teacher who had a popular TV show on PBS.

I love this name because Lilias is the name of the deceased wife of Archibald Craven, and mother of their son, Colin Craven, from The Secret Garden. The garden originally belonged to Lilias, and when she died Archibald locked it up in grief. Later, her spirit calls to him in a dream, telling him to return to the garden, and there he discovers that their once sickly son has become a healthy young boy.
