I am still looking for the original site. I'm seeing a new tourist site, that is not up yet when I try to go there and am hoping they did not take the old site down.
I found another guestbook at www.Basilicata.com
(the region where Potenza is). There is also the Vital Records Office at:
Soprintendenza Archivistica Perla Basiicata
Soprintendente, Mario Nenni
Viale Marconi, 104
85100 Potenza, Italia
(I'm not sure how far back their records go, but I was told I might have better luck contacting the church where my grand-mother was baptized. I'm just not sure of which church.)
