Oh I am sure there is a good reason, what the reason is I don't know.

Why Google Wants You to Google Yourself
I googled myself. I have a fairly unusual name and I don't use it socially online, so there wasn't much. Top results were for some guy in Germany, a Linkedin profile and a Yelp review for his book store. There were a couple mentions of my business and a listing on a genealogy site. After that were some similar names.
Maybe they're just warning you!
