Humm, I met a wacky Belinda as well! This must mean something!! (Well, unless we have a Belinda in common). 
Anyhoo - I have a totally rediculous name and I’m used as a “Normal Control” in psych studies all the time. I would have trouble believing that just an odd name could really correlate with any sort of meaning to clinical wackiness.
Finally, aasna, I think you’re mistaken. Increasing sample size will not create a correlation where previously there was none, it will just increase the accuracy of your conclusions as ** 12 parsecs** (or his wife) suggested.
