The parish registers of civil status, although the main sources of documentation for historical demography, are used with significant results by the other sciences such as history, ethnography, sociology, anthropology, linguistics, etc. The perspectives of approaching the rural community and family have expanded considerably using these sources of ecclesiastical origin documentaries. The first researchers who refer to a systematic methodology that uses the parish registers of civil status as documentary sources for the completion of demographic data suggest the use of other sources, hitherto unused for this purpose. They will apply a new method, a modern innovation, the stripping and analysis of parish registers of civil status within the meaning of the reconstruction of demographic events (birth, marriage, death). The family reconstitution method, by analyzing the parish registers of civil status proposed by L. Henry and M. Fleury, has revolutionized the field of study dealing with people. Louis Henry believes that the parish registers of civil status is the ultimate source of information for the pre-state period and this is precisely the reason for which he proposes restoring the family’s biological life. Church registers are only able to give us an insight into the family in rural areas, at least for the second half of the XIX century. Church documents, the fundamental sources for researching family life, are of two categories: 1. civil status registers and annual reports of the parishes, 2. Church authorities funds, documents and minutes recorded by the bishops. These documents are complex sources for the researcher interested in historical demography, social history, and the economic history of toponymy, birthdays, etc. Processing the data contained in these records requires a specific methodology. They allow us to observe trends that have occurred on the long-term demographic events such as: birth, marriage or death. These records are presented for a long time as their only source of documentation ...
