Query: not very deep research

I haven't read all of this book, but from what I've seen, some of the name meanings are wrong. This author has only repeated general superstition about where the manes come from instead of doing proper research into the names, it looks to me that she has googled some names and put them into print. You can pick up similar books like this on market stalls for a pound, but buy it if you aren't really that bothered whether it's correct or not.
