It's fine, I was just letting you know. I think Connor (or "Conner") showed up as Sly's father's name sometime around the release of Sly 3 (2005) as a fan name, and it stuck. Whoever came up with it is probably pretty proud of themselves because they've confused a whole heck of a lot of people.

According to some people, the name was also published as his true name in a Disney magazine, though Disney has no relation to Sly Cooper, and therefore have no say as to what his name is.
