Trying to find my family from Terralba, Sardegna

[Deiana7]

Hello, my mother is sardinian but I don't know her side of the family. Her parents are from Terralba, they left Sardinia in the 50s to go living in France. Their name are Roberto Casu and Elisena Migianu (or Mizzanu or Muggianu). They had 2 daughters when they left, Anna Rita and Pinuccia. I think my grandfather had a sister named Egle Casu. I also have some family in Genoa.

Thank you

Do you know when they were born, more or less?
