I have Di Cola's[ different spelling] in my tree, no Orlando's that I know of, but if GiorgiaSineni Liberto named one of her sons giacomo there had to be one in a previous generation according to the naming patterns in Sicily at that time., go back in your Sineni line and see who are the parents and grandparents and maybe that is where the tie is, or back in the Liberto's. The Di Cola in my tree would be Rosolia- who married Andrea Barbaccia in 1826. She was born in 1808.What block were those relatives living on? in America or Italy?
