I recently read The Types of the Irish Folktale by Sean ´O Súilleabháin and Reidar Th. Christiansen. This led me to the Schools' Collection - an effort by Irish folklorists to preserve old traditions by enlisting schoolchildren.
Fortunately for me, they are now in the process of digitizing this database! However, it took me a while to decipher the way the type index listed the examples of Type 700 found in the Schools collection. The website uses the format “The Schools’ Collection, Volume ----, Page ---.
A few interesting trends showed up as I went through this. Probably the most prominent trend is that I can't read Gaelic. Especially handwritten Gaelic. So much handwriting.
Variants of Thumbling
Variants of Thumbling that use the name “Tom Thumb”
Variants of the Young Giant
Other Tale Types
Gaelic, unable to read
Does not match
These were listed in the Type Index, but do not seem to be variants of Type 700. I may have made a mistake in transcription here.
This website is based on my research into folklore.
