Impact de la transmission du nom de famille par ordre alphabétique precedent

Abstract : Since 2005, the French legislation allows the transmission of parental surnames to the offspring in ways that are alternative to the traditional transmission of surname of the father. The surnames of both parents can be transmitted, but a choice about their order has to be made. This choice applies to the following generations too, however, the transmission of two double-surnames is not allowed. When there is no agreement among the parents about the order of surnames, or in case of adoption, the alphabetical order can be adopted. If alphabetical surname attributions take place at a high frequency, after some generations a large proportion of family names will start with a surname whose initial letter appears among the first one of the alphabet (A, B, C, etc.).In order to measure the time necessary for this phenomenon to take place, a mathematical model is applied here. The results show that the convergence toward the surnames beginning with A, B, or C would take several generations even with a relatively high frequency (1%) of this particular surname attribution. Thus, surnames beginning with A would double their frequency only after 20 generations.
