Thiersten family

[mumart]

Good morning,

I'm researching my family and found to the below.

Eduardo Christian Thiersten married 1869 Valletta to Maria Antoinette Pisano

With two sons
 
Alberto Theirstein, married to Maria Burlo
Ernest Christian Thiersten married 1887, Giuseppina Biasini

Does anyone has more information on Thiersten ancestors?  Or can guide me from where I can find more information?

Thanks
