What did the Early Church Fathers believe about the fate of the unreached?

Many individuals have died and continue to die without ever having heard the message of salvation. Illustrative examples of this are everyone who was born before Jesus, individuals contemporary to Jesus but too far away at the time to even have a chance to hear about Him in their lifetimes (e.g. Native Americans and all tribes from the Pre-Columbian era before the first missionaries arrived), isolated jungle tribes in Africa and the Amazon, and [uncontacted peoples](https://en.wikipedia.org/wiki/Uncontacted_peoples) in general. What did the Early Church Fathers believe about the fate of the unreached? Is there any hope for them to get saved, according to early patristic writings?
