Currently more popular for girls, Winsley could easily work as a unisex option, similar in sound to Winston and Finley. Literally meaning "Wine's clearing" and more figuratively meaning "friend's clearing", it briefly appeared in the US stats for boys in 2009.

A whimsical word name, Wishmay could reflect the phrase "Wish I may" or alternativel, "May all your wishes come true". It could then be connected with dreams, hopes, and fancies, adding to that whimsy feel.
 
Alternatively, it could be interpreted as with a wish for the month of May, or more figuratively, as a wish for sunnier, brighter weather. For a more grounded source, it may well be considered a twist or adaptation of the German surname Wischmeyer, meaning "tenant farmer who sweeps" or "tenant farmer from the meadow". 
 
As a given name, Wishmay is currently undiscovered, though it has received interest over on the Nameberry Forums alongside Loveday, Wildrose, and Maeblythe.
