What is your connection to the Pintarelli family?
My maternal grandfather was a Pintarelli from Crystal Falls, Michigan at the far west end of the Upper Peninsula.
His family immigrated from Pergine Valsugana, Italy in the provence of Trento. It is located just east of the city of Trento. There are many Pintarelli families there.
At the time of their immigration, the provence of Trento was part of Austria and considered part of South Tyrol. They were Austrian citizens. Now the area is part of Italy.
