My mother toured Canada with the Chataqua circuit in the 20s and 30s. Her British roommate was named Phyllida Lane: she returned to England and became Sir Laurence Olivier's diction coach. From various sources I have found that--supposedly--Phyllida also means, love of country, love in the country, a minor sea goddess,and a minor goddess of youth, and "leafy green bough" I can't cite specific sources because they were looked at long, long ago, or, in one case, a scholar of ancient languages, now deceased.
