Thanks, everyone, for the ideas. Sometimes we just need a fresh perspective.
Tessa, I will go back and make sure I haven't overlooked a border crossing; but these Cracatans (whom I am beginning to think of as 'those damned Leone's!'
) have a fairly steady pattern of Napoli-to-Manhattan migration. [These people are going to drive me right around the bend before it's over.]
Marty, your story made me smile. I spent years looking for my g-grandfather in the 1910 census indexes, to no avail. When I finally had access to the actual microfilmed pages, I scrolled right to the address where he should have been....and there he was. Pietro Roccanova...plain as day. Then I discovered he had been indexed as "Parks Borzahura." I had to laugh to keep from crying. (And, I too made sure I corrected the index at Ancestry. Now when you look for him...he shows up.
Roccanova/Magistra/Rubertone/Paduano of Craco, Matera, Basilicata AND Latorraca/Cassino/Petrocelli/Peluso of Saponara di Grumento (now Grumento Nova) & Moliterno, Potenza, Basilicata
