I came across the following : This record list Maria as "Maria Bonarrigo Landino" , I'm thinking that since it's a U.S. record and shows her as a Landino that she must of married ,"Frank Landino" in the U.S. - It's possible as you mention that Francesco and Maria could have been Common Law in Sicily prior to coming to America ....I will look for a death record .
