Congratulations.. you nailed it. Two breakers feed the circuit. Both 20 amp. One labeled family room, the other labeled dishwasher. Kitchen remodeled 8 years ago.Did you switch off all of the breakers at the same time or one by one?
It's possible, if an electrician has made a serious mistake, that these outlets could have been connected to more than one breaker.
Is there anything else in the house which doesn't appear to be fed from the main panel?
Can we leave it this way? Or is it a fire hazard.
