According to Delphine's dossier, she is in her mid 50's, so yes, I would say that Bretons do live slightly longer than Imperials or Nords.

Divayth Fyr is older than 4,000 years old if he is still alive during the events of skyrim

Also Yagrum Bagarn, Miraak, the Tribunal, and most likely the Volkihars.
