It is widely believed that the namegiven to man in the sacrament of baptism, is kept secret. However, this view is a fallacy. This is nothing more than a superstition associated with erroneous view of the sacrament of baptism as a mystical ritual, baptized protecting from distress and exposure to dark magical forces. Naming a person's name at baptism is primarily a sign of the introduction of personality "in the Church": name "world" should match name "in the Church." Thus the name "in the world" and the name "Church" differ generally only in the case that the name given to man at birth and was in the relevant evidence is not in the calendar. In this case, the name-giving at baptism chosen a nameclose to "worldly". For example, the name "Pauline" which is not in the calendar, often correspond to present there names "Pelagia" and "Apollinaire". So, the second namedifferent from the official, is not at all. But in any case, the nameassigned to a person at baptism is not a mystery, and pronounced publicly and recorded in specific documents.

The second way is to find a baptism certificate that shows this information. A baptism certificate can be stored as direct and godparents are baptized.
If the required information zapamatovat family, a baptism certificate is lost, you need to find a Church in which the baptism was carried out, and to go to the stored metric lists, which contains data on all persons baptized in this Church.
