The article presents a demographic description of reconstructed families in the Parish of Nowy Korczyn in the second half of the 18th century. The description has been made thanks to the method of family reconstruction recognised in demography, created by Louis Henry, which consists in assigning all events recorded in the parish registers to married couples. As a result, 265 closed families and 317 open families have been reconstructed. Additionally, the research has included the so called complete families. Three series of parish registers of Nowy Korczyn kept in the Diocesan Archives in Kielce were the source basis for the research. The completeness of the records varied considerably. The results obtained turned out to be similar to the ones observed before: a higher percentage of premarital conceptions older women, extension of the inter-genetic interval in case of the death of the previous child before it reached the age of one year, the longest latest interval between childbirths, widowers contracting new marriages faster than widows, the correlation between contracting a new marriage and the number of living children.
