I spent most of my time manually auditing
automatically matched entries
from the Dizionario Biografico degli Italiani [2].
Thank you! That's very useful. I did some thousands too. :)
My favorite example? Mix’n’ match suggested a match
between /Giulio
Baldigara /(Q1010811 <https://www.wikidata.org/wiki/Q1010811>) and
/Giulio Baldigara/ (DBI
<http://www.treccani.it/enciclopedia/giulio-baldigara_%28Dizionario_Biografico%29/>)
which looked totally legitimate: these two individuals are both Italian
architects from the 16th century with the same name, they were both born
around the same years in the same city, they were both active in Hungary
at the same time: strong indication that they are the same person,
right? It turns out they are brothers and the full name of the person
referenced in Wikidata is /Giulio Cesare Baldigara/ (the least known in
a family of architects). I unmatched the suggestion and flagged the DBI
entry as non existing in Wikidata.
Yes, this happens every now and then with Europeans that time, also with
father and son having very same name and very same field of activity or
even publications.
Creating an item is good, as long as you have at least one piece of
distinguishing information.
The standard practice (at least on it.wiki) in such very ambiguous
cases is to add a disambiguation page or note, even if the target
article doesn't exist yet. In
https://it.wikipedia.org/wiki/Antonio_Montanari I went the extra mile
and also added more information, including a source: you can go into any
level of detail, unlike on Wikidata.
I encourage you to create a disambiguation page at
https://it.wikipedia.org/wiki/Giulio_Baldigara with all the information
you told us here (policy reference:
https://it.wikipedia.org/wiki/Aiuto:Disambiguazione#Link_rossi ).
