There is probably a relationship back a bit. My wife's maternal grandfather was Giovanni Troisi who came from Grottaminarda in Avellino. There are records that suggest that he married a woman named Nicoletta in Sturno, Avellina Province, had three children, moved to the USA in 1909 and married my wife's maternal grandmother, Maria Cangero, also from Sturno. If the facts we have found do apply to my wife's people then there is quite a story there. So far, it all seems to bear out. Needless to say, I would like to get an Italian researcher to do some more digging.
