Antonia Diponio Cassino Area

Hello,
We think our Granny's mother may have been called Antonia Deponio. My Granny was called Francesca Dinallo and she had a brother called Pasqualle. She was born in 1896 in the Cassino are of Italy. I have seen a family tree on here with the names Antonia Deponio and Pasqualle as her son but I don't know how to contact the tree owner.
Hoping someone can help!
