Celtic Fairies: Celtic Fairy People

I think it is a common misinterpretation that there is only one type of fairy such as the the,well know Tinkerbell. I have recently discovered that there are at least three different kinds of fairy people. One type is a creature that goes by the name of a changeling. This is interesting because until now I had no idea that was such a mythical creature existed in fairy tales. A changeling is when a fairies baby that has ,unknowingly by mortals, been replaced that of a human baby. In turn the humans baby is taken by the fairy(s) ( Celtic Mythology). I believe that these particular fairies are unique in that they must resemble human like characteristics in order to stand as mortal baby. The second kind of fairy is a social fairy. These fairies lives in rather large groups almost like native American tribes; also called clans (Celtic Mythology). It has also been believed that social or trooping fairies are fallen angles who are here to do the work of the heavens in making sure that good is brought to the good natured and evil stays among the evil hearted (Yeats). The third type of fairy people's is the solitary fairies. These fairies, In my opinion, wanna remain in isolation, keep to themselves, and not be part of a clan or group of fairies. Through out my research I have stumbled upon the facts that these fairies wore red jackets to distinguish themselves from the trooper fairies (Yeats).
