Slightly off topic, but does anyone have experience with there being a tradition of researching family histories and genealogy among later generation immigrant families in nations outside the US?

I’ve had multiple friends and relations start researching their family history with the intent of finding the first ancestor to immigrate to the US and their country of origin. As some others have said, I don’t believe these people consider themselves to truly be a part of that culture, but it’s a fun bit of personal trivia and some fresh new traditions to explore, so it gets talked about.

I wonder if that’s universal, or if it could be more of a phenomenon in the US and contributing to what the OP is observing.
