DeSanctis and Manzi from Castelgrande

Both grandparents emigrated to NY from Castelgrande sometime in the 1890's (?) I know next to nothing about their origins save that health records indicate both were from Castelgrande; my grandmother's maiden name was Manzi; she had a brother named Abel who emigrated to Argentina (I think); beyond this I know very little. I do know that my grandfather Angelo DeSanctis was a founder of "The Young Men's Society of Castelgrande," which evidently disappeared shortly before or after his death in 1963.
