Generally -sama is one of the few suffixes that is translated. It would be either Lord or Lady. -dono doesn't seem to have an equivalent. -kun, -chan and sometimes the first name basis difference are omitted in dubs but they do sometimes keep -sensei and shishou. And the various different ways to address people like Mother and Father are made less apparent in dubs. When I read manga its translated as "Mother"=formal speak and "Mom"=informal speak but in Japanese it would be Hahaue or Okaa-sama formal and Kaa-chan or Mama informal. End of lecture =P
