Cyber Stalking is very real and a growing problem. 8 years ago someone my wife ran into at work saw her name badge. Later he said he found out everything about her and was going to intrude on her life (not in those exact words obviously). But what my didn't tell him was who she was married to and everything he found was either 'planted' information by me or not even her information at all. All of it was a dead end.
I've learned a long time ago the importance of maintaining some level of privacy/anonymity. I'm a ghost online. My real name doesn't exist as a searchable entity and I haven't used it online in a decade. I have a dozen assumed identities. My home address while searchable isn't tied to a real name. Google Maps is blackened out on my street. My tax, county and state records are all privatized. I've recently extended this level of privacy/anonymity to my wife and children who are now ghosts online.
The good thing is - once you take control of all of this it's very easy to maintain. Just check yourself on search engines once or twice a year and file privacy/opt-out forms to knock yourself off anything you re-appear on. It's far better to get a handle on this as early as possible than it will be in the future to attempt to regain control after the dam breaks on all of your stuff. It's far easier to keep control than it is to regain control. For example if photos get out there, they'll be there forever.
Also there are services that can help. Some are free, some cheap, some expensive, some maintain it forever for you. Also I recommend removing/deleting extraneous accounts you no longer use to reduce your exposure and threat surface.
