Hello Lisa.
I have some info on the Arcaro Family. There are many many Arcaro's in Italy and in Montreal Canada. The Arcaro's came from a village that was once called S. Angelo in Grotte which today is known as S. Maria Del Molise. S. Maria del Molise was once part of Campobasso but in 1958 it became part of Isernia. I know many Arcaro's and I'm even related to some. If you need more info please feel free to contact me. I'm currently reseaching my family tree. Since our families are from the same village we can help each other out. Who know's we may be related.
ciao
