I have every reason to believe that my grandfather Giovanni LaFianza and his two brothers Raffaele and Camillo were all born between 1879 and 1885 in Ferrandina (Matera, Basilicata). However, in searching through both the town's birth records and that of the church there for all the 1870's and 1880's (I was there personally two days ago - awesome!), no record of there births could be found. I did find, however, a birth record for a Giuseppa LaFianza in 1877 and a death record for her in 1883. The mother's name was listed as "Rosaria LaFianza", who I know for certain is the mother to the three males I've mentioned, making them brothers of Giuseppa, with "padre ignoti", or unknown father, for the father's name. Hence, all four children took the monther's last name. I've checked every other town in the Matera region and there are no LaFianza's at all - it was and is still today a very rare name. With Giuseppa being born and passing away in Ferrandina, it's highly unlikely that they were anywhere other than Ferrandina all this time. Why can't I find birth records for the three males? Is it possible they were not reported due to their illegitimacy? Many thanks for your help.
