I may have to check these folks out. I’ll definitely be taking their online survey of faery beliefs.
The Fairy Investigation Society (FIS) was founded in 1927 by a British man named Quentin Crauford. Attracting mostly Theosophists who believed that fairies were elemental beings, the Society continued sporadically through the 20th century until finally disappearing in the 1990s.
In 2013 the Society was re-booted by Simon Young, an English historian living in Italy. While membership in the original Society was limited to people who believed in fairies, the current society is open to “all those who have an interest in fairylore, be they believers or ultra skeptics.” I’m proud to be a member myself!
