With the Treaty of Vienna in 1815, Trentino was annexed to the Tyrol County. From that year until after the Great War – until December 31st, 1923, to be precise – the birth registers were maintained by the parishes, which also acted as registry offices.
While many registry rolls were lost, those remaining were transferred onto microfilm in the 1980s to facilitate consultation.
The details of these individuals (approximately 1.28 million in all) have now been collected, in a project lasting several years, in an Index made available to academics and anyone wishing to retrace the history of their family.
