Davidson family play musical instruments. L'Engle's young heroines are sometimes compared to the author herself as a teenager, with some of the protagonists experiencing fictionalized versions of settings and incidents from L'Engle's youth. For example, Flip Hunter and Katherine Forrester both attend a Swiss boarding school, as did L'Engle. However, in a 1963 article, L'Engle's husband, Hugh Franklin, professed to see the adult version of the author more clearly in the protagonists' mothers, Mrs. Murry (Dr. Kate Murry) and Mrs. Austin. The only characters acknowledged by L'Engle as being directly based on a real person were Rob Austin, who was based in her son, Bion Franklin; Canon Tallis, who was based on her spiritual advisor, Episcopal Canon Edward Nason West; and Bishop Nason Colubra, based on David Somerville, a retired archbishop of Vancouver.
