Aenghus, Gnome of Love after the god Aenghus Og from Celtic folklore.  I chose him for his correlation to Imbolc , love, poetry and youth. 
For this one I was inspired by one of Aenghus's stories from Irish mythology. He dreamt about his true love.  She happened to be the goddess Caer Ibormeith who shapeshifts into a swan every second Samhain.  In order to marry her, and break the spell, he had to pick her out of a flock of over 150 other swans.  He did.  Hooray! 
This is a very basic overview of the tale, but what a wonderful love story.
