Older house?? Code requires two 20A GFCI protected dedicated circuits for countertop outlets. (1) The outlets in question may not be on the same circuit as your working GFCI, look for another GFCI. (2), They could be on the same circuit, but have a loose wire in the chain, which could ba a hot or neutral anywhere in the chain. (3) Older house may not have two circuits, may share loads with other things, but the culprit could still be a loose connection. Backstab outlets are a continuing problem in older houses. The backstab contacts loosen over time and eventually don't work.
