To be fair, it’s a bit confusing. The city of New Orleans ( gnu aw Lunz) is located in “Or Leanz” parish which also has a major street named “or Leanz” ave. Food for Thawt.
Back in the 20th century, Garland Robinette on WWL news, IIRC from St. Charles Parish, used to pronounce it Nyuu OR-lee-unz, even though I think Nyuu OR-lens is more common.
