Self-Similarity in Population Dynamics: Surname Distributions and Genealogical Trees
Entropy, 2015 The frequency distribution of surnames turns out to be a relevant issue not only in historical demography but also in population biology, and especially in genetics, since surnames tend to behave like neutral genes and propagate like Y chromosomes.

Ripples on the surface. Surnames and genes in Sicily and Southern Italy
Annals of Human Biology, 2018 Background: Southern Italy and Sicily played a key role in the peopling history of the Mediterranean. While genetic research showed the remarkable homogeneity of these regions, surname-based studies instead suggested low population mobility, hence ...

Surnames in ferrara: distribution, isonymy and levels of inbreeding
Annals of Human Biology, 1987 The distributions of surnames in populations of small and large towns are almost exactly linearized by a log-log transformation. This indicates probable fit of genetic models to most such distributions, even when the number of surnames is very large. Genetic parameters can then be conveniently calculated from surname distributions.

A Probability Model Involving the Use of the Zero-Truncated Yule Distribution for Analysing Surname Data [PDF]
, 1989 In this paper, a probability model leading to a Yule distribution is developed in the study of surname frequency data. This distribution, suitably truncated, is fitted to actual data as an alternative to the discrete Pareto distribution, with quite ...

The distribution and geographical origin of some French surnames
Annals of Human Biology, 2000 The geographical distribution of the principal form of a French surname and its close variants (in spelling or pronunciation) has been analysed based on the French births registers, respectively from 1891 to 1915 and from 1916 to 1940, and on telephone directories for 1975.

Universal features of surname distribution in a subsample of a growing population [PDF]
Journal of Theoretical Biology, 2010 We examine the problem of family size statistics (the number of individuals carrying the same surname, or the same DNA sequence) in a given size subsample of an exponentially growing population. We approach the problem from two directions. In the first, we construct the family size distribution for the subsample from the stable distribution for the ...

Footprints of middle ages kingdoms are still visible in the contemporary surname structure of Spain.
PLoS ONE, 2015 To assess whether the present-day geographical variability of Spanish surnames mirrors historical phenomena occurred at the times of their introduction (13th-16th century), and to infer the possible effect of foreign immigration (about 11% of present-day)
