I am a public employee, so my pay and job title are online. As for the public records with your county, you may be able to block the information, however, it is is still transparent on sites like Trulia with a google search of your name.
My husbands family tree came up. I guess someone started it and posted it online or worked on one via an online site. I find the family tree on that side of the family funny because his grandmother was so private she had her first initial and last name on her checks, with no address. As well, they all have PO Boxes.
Also, social security numbers of dead people will come up too. When I google my dad's name a photo of his head stone comes up.
For those with common names, the trick is to google first name, last name, city, and state. That is unless you have a name like Pat Lee.
