Looking for Relatives of Secundini Lanni from Cassino Italy

My Gt Gt Grandfather was called Secundini Lanni he came from Cassino, Italy and had a daughter called Mariantonia who was born in Cassino in about 1872. She married my Gt Grandfather Benedetto Fascione in 1893 in Southport, England and they had 2 children but sadly she became ill and returned to Cassino where she passed away in about 1889. Does anyone have any info on this branch of the Lanni family?
