 This type of information is often difficult to obtain, especially in cases where birth certificates and baptismal certificates were intentionally falsified; legal documents are filed as concealed records not readily available to the public without a search warrant; or when persons of interest are deceased, uncooperative, or desire not to be found.The majority of clients are children who were orphaned, fostered, or adopted seeking to learn about, contact even reunite with their biological relatives.Others include parents separated from their biological children; doctors benefiting from family medical histories; attorneys dealing with inheritance or other legal matters; police detectives researching crimes, requesting DNA, or other confidential personal information; historians, genealogists, and social researchers; and other individuals requesting information about ancestral antecedents.
