I agree that names should be pronounced the way that the "owner" of the name pronounces it. I find it funny that I always mispronounced both Centuri and Estes as a kid. Estes is a family name, and Vern pronounces it "ess tess." Lee Piester named Centuri, so it is pronounced the way that he calls it (with I think is sen-TUR-ee).
Locally, everybody called Estes "es-tees" and Centuri "Century", but then again Rochester has a lot of unusual pronunciations. One neighborhood in Rochester is named Charlotte, and it is named after a woman named Charlotte, but it is pronounced "shar-LOTT." The suburb Chili is named after the country Chile, but it is spelled with an "i" at the end, and it is pronounced "cheye leye." The town of Avon is pronounced "eh von." The town of LeRoy is named after someone with the last name of LeRoy, and many locals correctly pronounce it "leh roy" (not "lee roy").
