In this work the author by making use of parochial archives in Busnago (Milan) has controlled the long life proceeding of 187 among the 259 twins-pairs numbered during a period of three centuries (1632-1962). The author has verified the mothers' age at the moment of childbirth.

He has been able to point out a greatest concordance in the average life time of the MZ pairs in comparison with the DZ ones, which agrees with the hypothesis of a genetic long life factor. The mothers' average age, studied on a small group of population during a period of three centuries resulted, in the 159 cases the author could peruse, to be from 30 to 35 years, of age in agreement with the data collected by Gedda on the global Italian population during short periods of time.

This average age supports the hypothesis that among the factors of multiple pregnancies may be numbered besides mothers' age a geographic (racial) variability.
