Giulio Cesare 1673

Giulio Cesare was born about 1673. (More likely to be later than this)
His father was perhaps  called Giovanni Zani  
He married Angela Bertuzzi

NHG could not find his birth certificate in Bologna
although Negri claimed to have seen it there
However without seeing and checking it we cannot be certain that his father is Giovani.
This is as far back as we can definitely go at the moment

Giulio Cesare and Angela Bertuzzi had
Giovanni Battista Zani born 1712
