Every year more and more people are finding the excitement and interest of tracing their family history. In researching ancestors one should start research-work by collecting facts known by relatives. Then, one can carry on research in institutions where public data, registers or the copy of these can be found. GENEALOGY is an investigation during which the researcher deals with birth, marriage and death registers and the indices of them. He or she may get acquainted with last-wills, censuses of noble people and of bourgeois, special literature of Genealogy and with several other church and archive sources. Following this road the researcher will, with some luck and a lot of research work of feverish activity, and of excitement, be able to construct his family-tree back two or three centuries.
