The ethnic structure of this region has been strongly influenced by the evolution of different historical-geographical, and political factors, but also by the evolution of the confessional structure. Ethnicity, from this point of view, is closely related to religion. What is typical and important to note is that the ethnic structure is very diverse. In addition to Romanians and Hungarians, also Gypsies, Germans, Slovaks, Jews, Ruthenians, and Serbs are present; other ethnic groups are numerically insignificant. For this period we identified two important categories of documents relating to ethnic identity of Transylvanians: 1. records made by the Austrian state authorities; 2. Church documents. They must be viewed and analyzed with great care because they do not correspond directly to the necessity to establish ethnic identities. The documents that are available to us do not allow for an accurate determination of a person's ethnicity. Given the lack of a variable on nationality from the few censuses conducted by the Hungarian State, we propose based on analysis of other documents (particularly those of ecclesiastical origin) to: a) check the mother tongue, b) establish religious identity and c) run an onomastic study.
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 regarding civil status and demographic events in the life of most people. Researching these records can unveil important features of natural population movement, the phenomenon of birth, of marriage, the divorce or death. Then, an analysis of form and content of these registers can capture the cultural universe of the priests who fill these records. These Church documents proved to be important, especially where other documentary sources (mainly those in the category of records made by the state) have proved insufficient, incomplete and unclear. The parish registers of civil status in this case are suitable for both a qualitative analysis, and a quantitative one at the level of local communities. Beyond their usefulness and significance of documentary source, these documents should be regarded as being subjective because they were managed by priests (every priest is then an exponent to promote demographic and confessional "realities" and such realities were viewed from the perspective of his own religious convictions). The parish registers, however, prove to be the only documents that allow us to penetrate the privacy of individuals in each community. A documentary is also undeniably a good dowry that researchers should promote and use in their research not only locally but also to verify and demonstrate certain behaviours and overall trends.
A marriage amongst youth belonging to the Greek-Catholic and Orthodox confessions was considered almost normal in certain communities. This can be explained by the fact that few parishioners could grasp the differences between the two confessions. At the same time, we have the ethnical aspect. Ethnie could not be separated in this case from confession, as both Greek-Catholics and Orthodox in the area are mostly of Romanian ethnie. These elements should be considered especially since we considered a mainly rural area, where customs "laws" are superposed over the official ones. On the other hand, in the mixed Greek-Catholic and Roman-Catholic communities, inter-confessional marriages are easier accepted on the "official" level. An important constraint, or, on the contrary, a strong determination against a mixed inter-confessional family came from the families. As mentioned before, a strong pressure against achieving a mixed marriage came from the church. Both parishes to which the youngsters belonged had to be consulted. In order to have a religious marriage, they needed an engagement exemption from the archpriest (they came weeks, even months late, there were situations when the marriages were not accepted, so there would be no exemption). They had to pay a large amount for the exemption, so that many youngsters could not afford to pay for it; this was often solved by clandestine "wild" marriage. However, both the State and the Church wished to stop this phenomenon, so they took steps in this area.
The historical-demographic approach of family in their relationship with society with different transitory societal or community typologies is a complex initiative that needs a methodological approach including peripheral elements as well, besides a deep analysis on the central defining elements. The historical demography and other sciences, such as anthropology or history of mentalities, by directly or collaterally approaching the family, often make references to the three important moments in the individual's life: birth, marriage and death. We have used several categories of documentary sources in our survey. We have the information on the population in north-western Romania due to the ecclesiastic notes (in the parish records or reports and the bishopric notes); on the other hand, we have the information provided by the Austrian and Austro-Hungarian state. Methodologically, the first phase of our research consisted of the preparation of the documents investigation strategy, as expected. In our research, we consider the fact that we approach the area of ecclesiastic entities, as most of our sources for the 19th century belong to the church. This imposes a stress on the confession and its importance. Besides confession, an aspect that we wish to underline is ethnicity. In our investigation on the family the main stress was laid on the survey and analysis of different marital behaviours. Through different constraints and determinisms entailed by the possibility to choose, marriage is highly relevant in establishing behavioural laws (if they ever existed!?). The dimension of the marital market corroborated with the ethno-confessional and socio-professional realities provided the particularities of the marital phenomenon. Referring to the lay and ecclesiastic legal framework, we support the need for a flexible approach of the topic. The logic of this foray consists of the visualisation of the legal framework – rigid and impregnated with an obvious moralising discourse – on the one hand, and the image of conformism and means of adaptation of the individual, on the other hand. The starting point of the family is marriage. If we approach marriage from the point of view of the confessional and ethnic conditioning, we get to an analysis of the mixed marriages phenomenon. In fact, the analysis of the ethno-confessional and socio-professional determinisms and of other types of community or individual conditions can be easily carried out in the case of mixed marriages. The central point of our research is the analysis of Romanians', Hungarians', and Germans' marital behaviours without ignoring the image of this phenomenon at other populations in the area. An analysis on birth and death rate, or natural growth, is able to provide information on the impact demographic phenomena had upon family. A world where death rate was very high and where family would react through a high birth rate was undoubtedly influenced by the demographic flow. Irrespective of the society typology, divorce, concubinage, and illegitimacy (no matter their way of manifestation) were forms of social deviance leading to the dilution of family image and precepts. We do not discuss here a dilution of the traditional precepts on the family, as someone might misunderstand; it is an erosion of the idea of family in general. The "family" began to acquire other forms than the "official" ones. From the relationship of the family with the community were born mentalities, roles and social statuses. The family, its formation, the relationships between man, woman, children and relatives, as well as the relationships with the rest of the community were filtered by the "village gossip". The need for a strong solidarity that was necessary in the unfriendly conditions at the time compelled the individuals to accept the cohabitation with other members of the family (including the extended one) and with the rest of the community.
