I found out last night that I am and so are the rest of my family eligible for EU Citizenship (Italian ) as my great-great-grandfather was born in Italy and never renounced his Italian Citizenship, Italy has a rule whereby if one of your ancestors was ever a citizen and never renounced their citizenship before death or when moving to another country then you have the right to be an Italian as well. However the process to get that is to get every birth, marriage and death certificate for every ancestor back to the source which sounds like an enormous task.
