Actually looking for information on Pietro's father - Giacomo Pierachini. Farmer/Gardener. Italy.
Unfortunately the last name has been constantly misspelt for generations, so accuracy regarding the proper spelling is hard. However on the documents of Pietro and Giacomo they both read as Pierachini.
Quite possibly Giacomo might have come to visit Pietro to see his grand children in 1837, from Pietro's first marriage to Margaret Brady.
Document I found:
Giacomo Perusini

Could this be misspelt again, and actually be Pierachini.
Port of Arrival: London, England
Arrival Date: 13 Apr 1837
Country of Origin/Native of: Italy
Class: HO 2
Certificate Number: 1560
If anyone could give me any information on Giacomo, I would appreciate it. I would estimate his birth in Italy would be around 1770 to to 1790.
Thanks.
