While many fairies will confuse travelers on the path, the will o' the wisp can be avoided by not following it. Certain locations, known to be haunts of fairies, are to be avoided; C. S. Lewis reported hearing of a cottage more feared for its reported fairies than its reported ghost.  In particular, digging in fairy hills was unwise. Paths that the fairies travel are also wise to avoid. Home-owners have knocked corners from houses because the corner blocked the fairy path,  and cottages have been built with the front and back doors in line, so that the owners could, in need, leave them both open and let the fairies troop through all night.  Locations such as fairy forts were left undisturbed; even cutting brush on fairy forts was reputed to be the death of those who performed the act.  Fairy trees, such as thorn trees , were dangerous to chop down; one such tree was left alone in Scotland, though it prevented a road being widened for seventy years. 
Wilde was declared bankrupt to pay legal costs after his conviction for " gross indecency ", and his possessions - including manuscripts, letters, books and presentation volumes of all the major literary figures of his day - were sold by auction. This has made bibliographical (and biographical) studies of unpublished work more difficult since they are widely dispersed, some in private ownership. The largest collection of Wilde's letters, manuscripts, and other material relating to his literary circle are housed at the William Andrews Clark Memorial Library .   A number of Wilde's letters and manuscripts can also be found at The British Library , as well as public and private collections throughout Britain, the United States and France.
When you say “where are the mothers” I think you are missing the point. In fairy tales the literal mother may be missing–she dies on the first page (Cinderella), or she just drops out of the story (Rapunzel)–but that’s just so the fairy tale can get about the business of depicting all of our mothers in their most wonderful or horrible aspects through the metaphor of the fairy god-mother or the wicked witch or the evil queen. These tend to be the strongest characters in fairy tale, and they’re all about mom.
