Hi, hope this is not late (I see the message was posted on2002!). Well, I'm from Italy my grand-father was Luigi Lammardo, from a little town called Sala Consilina (not far from Naples). Some of his brothers went to USA, I don't so much about it, it was around 1920. The latest news I heard was about my grand-father's brother's son, called Rosario Lammardo, living in New York (Brooklin). I don't have any notice about relatives in Ascoli Piceno nor Macerata, but one never knows.
Hope you have luck!
