Children of Morta

I've done 5 or 6 of these so far, where you run into another member of your family and help them out, but none of them have counted.

OK, finally got 20% towards this one. I think I may have figured it out. You might have to do the event, but then finish the dungeon run for it to count. You can't quit or die. I know I did 2-3 of them in runs where I died or quit out. Or I could be wrong and for some reason the others didn't count, and this time getting the Wolf Cub's house built from wood I found is what counted. Guess I need to test this more.

OK scratch that, just did one where I helped Uncle Ben by finding wood to repair someone's cart, and the tracker did update right away. I got the Board Game souvenir as well from the event. So either they added in more of these events in updates to the game, and those later specific ones don't count for this achievement, or it's just kinda glitchy what counts. The two I know that don't count for anything are one where you help a family member charge up a type of magic tower, and helping a family member go through a small section killing enemies to save some villagers. Oh, those are literally mentioned in the guide, lol. Well maybe they were glitched in an update after this guide was made.

I can confirm that this achievement doesn't only include encounters that involve another Bergson. I unlocked this by completing the event where you rescue a bear that is being tortured by thieves. It also didn't pop right away.

It unlocked after I rescued Mary and returned home. There was a scene in which the family found some fruit that the bear left as a token of gratitude. I'm guessing that is the point when this event is actually marked as complete. So, if an event doesn't seem to be counting towards your progress, head home and check if an additional scene is triggered. So much for "in-run".
