Hi,
I have an old data about the pizanti / pizante surnames in Turkey by the city telphone book in 1973-78 of istanbul city.
Once up on a time, I was searching the old books in istabul
I found that old telephone book and I've started to search my surname , " pizan ". And I found my family phone numbers but also the other surnames pizanti / pizante . I blieve that
it's the same surname , just because of differences of pronaunsation ( te = ti ) But I did not buy that book, May be
Turkish telephone company web site helps you to search.
Here is the link,
