No. They DO NOT.
The following is a key aspect of Buddha Dhamma and that can avoid many unnecessary speculations about kamma/kamma vipaka.
Kamma are committed BY THE MIND.
– If one thinks, speaks, and acts with greed, anger, ignorance, those are the root causes.
– Kammic energy is PRODUCED in javana citta.
If those children helped their father in his immoral activities (and thus generated defiled THOUGHTS) then they would create THEIR OWN kamma and the corresponding vipaka will come to them.
– That has nothing to do with the kamma/kamma vipaka that the father created for himself.
