Hello Persivale Family,
I am a descendant of the Persivale/Percivale line from Genova and I have done quite a bit of research on this line through my cousins in Genova. The history of the Persivale/Percivale family goes back to the 1600's in Italy. The name supposedly comes from and Englishman, named "Persival", who settled there in the 1600's, then the family eventually italianized the name to "Percivale". Either spelling is not common in Italy except for the Genova area and then running north up the Scrivia River Valley to Milano, though it becomes less common as you go northward to Milano. "Percivale" is the most common spelling, though my cousins in Genova spell it both ways.The cousins that spell it "Persivale" do so because some of their ancestors/relatives headed to South America (mainly Argentina and then Peru) in the 1800's and changed the spelling to "Persivale". Some returned to Italy and kept this spelling. All Percivale/Persivale descendants probably share this link and are related, though the connection may be back 100's of years ago. My brother Adam, a "Percivale" descendant that settled in California, married a "Persivale" descendant whose family settled in Peru (her family is the Rodriquez/Persivale group some have mentioned); there are also a lot of cousins in Argentina. Basically, if you want to trace the Persivale/Percivale family tree from Italy, it all leads back to Genova. I have my family tree with a Percivale/Persivale family tree at my website: www.cassano.homestead.com
However, I only list back to my great great grandfather, Antonio Persivale.
