My name is Fabio Lucano. My father grandfather migrated from Caulonia in the late '50s to Adelaide, Australia. When i saw your name "Yacobet", it reminded me immediately of a name i know here of an italian family called Jacopetta.
The reason i bring this up is because my mother's maiden name is Scuteri. Some migrants with this name were forced to change it by the italian government before leaving for australia. There are a few familys here in Adelaide with the surname, 'Scutter' and I know for a fact that this was what the italian government changed Scuteri to.
If you are interested in tracking up your line of Yacobet, search for Jacopetta.
