Pietro Giuseppe came from Tavernerio, a small village a few kilometers east of Como. I do not have proof but it is highly likely, as several other Ronchetti's are known to have come from this place and were instrument makers. His father was possibly named Francesco and his mother Vittoria.
Pietro identified himself in England as either Peter Joseph or simply Joseph. He, his wife Mary Ann and his eldest son Francis are buried in the Victorian section of York cemetery. Sadly the grave is overgrown and the stone is badly deteriorated but the names are quite clear. An adjacent grave contains the remains of Hannah Gee (Mary Ann's sister), and Sophie and Elizabeth two daughters of Pietro and Mary Ann.
I hope this is helpful.
