Interesting bunch!
Delysia is a strange one. According to the records it seems to have appeared out of nowhere in 1916, and there's a steady trickle of them after that. I wonder where it came from?
Gwendyth looks like a transcription of Gwendydd -
Merlin's twin sister in some stories, it's not been used much in Wales.
Gwithian is a place in Cornwall - makes an interesting name.
Awwwwww 94-yr-old
Bunny! And how awful about 17-yr-old
Horatio, very sad for his marvellously named brothers.
