If you’ve ever set up an account on-line that requires a password, you may have had to choose some security questions which you need to answer if you forget your password.  A common choice is “mother’s maiden name.”  Sure, you figure, who is going to know your mother’s maiden name besides  a few carefully selected people or your closest relatives. Well, if you have your tree posted on any of the many family tree websites OR if one of your carefully chosen relatives has posted your tree on-line, OR if any of the millions of people out there who look at trees and incorporate almost every bit of information in anyone’s tree into their own, then almost EVERYONE has public access to your mother’s maiden name.  Choose something else, please, and make sure it is not something that is going to show up on a family tree database.
