The missing person search seeks to locate parties who may or may not want to be found. The missing person search is used to find long lost friends, lovers, and relatives. Locate searches are also used in cases of adoption, as you may need to find your birth parents to learn of your medical history, or you may be a biological parent (birth mother, birth father) looking for children given up at birth for adoption.
There are several levels of inquiry to missing person search. In some cases, such as finding long lost friends, lovers, and relatives who have just drifted away, you may have a fair amount of information about them already, such as last known address and date of birth. For other types of locate searches, you may not have any such vital data or the information you have may be decades old. These cases are more challenging, but they are solvable.
A couple of factors determine the level of difficulty in a missing person search where there is little more than a name to start with. The first factor is how common is the person’s name. If the last name is Smith or Jones and the first is fairly common, the task is more difficult. The second factor is name changes. Women generally change their names when they get married. This presents some of the more difficult locate projects, especially when the date of birth is unknown.
