No and there is something you can do: don't buy them. My rule is that any book/website that links the words 'Baby' and 'Names' are inherently crap and to be avoided with absolute vigilence.
I look for 'Lexicon' and 'Dictionary'....boring words that show a distinct lack of sales initiative. And I'm picking about my press....if they publish cook books I'm not really interested. And I look for linguistic references - ie. (Greek) beautiful maiden isn't enough, I want to see from the Greek kalos 'beauty' blah blah blah. Even then, humans are fallible and no one knows everything. They may be able to list 20,000 names but they'll no nothing about most of them....small, specialty.
I like the obscure ones put out by obsessed researchers - Names of the Indian Sub-Continent - try used book shops and jumble sales. For some reason they tend to end up in those sort of places.
