I AM STARTING MY FAMILY TREE EVEN THOUGH I AM ADPOTED MY MOTHER WAS ITAILIAN. MY GRANDFATERS LAST NAME WAS GRAPPONE AND MY GRANDMA'S NAME WAS MAINO BEFORE SHE GOT MARRIED. SO I AM JUST TRYING TO FIND OUT WHERE MY FAMILY LIES.
Surname Grappone is very local to the area of Avellino (southern Italy), while Maino is very common throughout northern Italy (Lombardy, Veneto, Piedmont). More info is needed to start a search. What information do you have (first names, places, dates etc) ?
Oops! I didn't notice that you put Miano in the subject line and Maino in the text. Miano makes much more sense coming from exactly the same area of the husband. Just a small difference and the surname moves away 800 kilometers!
