Migration through surnames in Campobasso Province, Italy

Data on grandparental surnames were obtained from schoolchildren in 22 comm unes from Campobasso Province, Italy (Molise Region). The distribution of s urnames was shown to be almost exactly linear by a log(2)-log(2) transforma tion, which justified the fitting of the data to Fisher's logarithmic distr ibution. The values for nu were higher among women. When nu was standardize d to minimize bias due to sample size, the value was one-third the estimate of migration from exogamy data. The higher values of nu for females indica te that there is greater mobility of female marriage partners than males.
