I can't help w/ improving your accuracy, but would very much like to know how we can access the info. I'm particularly interested in finding info re. the marriage of my maternal ggmother & ggfather:

Angela Marenzi (dau, of Caroline & Antonio Marenzi)
Birth about 1858 in Pregola di Pavia?, Lombardia, Italy
Death 21 Oct 1939 in Bronx, New York, USA

Guiseppe / Giuseppe Orsi
Birth in Brallo di Pregola, Piemonte, Italy
Death Bef. Oct. 1905 in Genoa?, Genova, Liguria, Italy (?)

Many thanks!
