I'm very happy for your successfully researches :)
Like you I'm trying to link families each other.
So... The mother of my great grandfather was Maria Quagliaroli; she was born in Rocconi and she married another Quagliaroli, from Volpi near Rocconi (do you know the "legend of the three Quagliaroli's brothers"?) who named Vincenzo.
They had a son in 1865, Antonio, the father of my great grandfather.
Do you know Maria? Is linked to Quagliaroli\Draghi\Tavarella?
Please help me
In geneanet you can visit my family-tree with 19 Quagliaroli.
