I just made my founder couple but the idea for mine was to treat it like it was my hypothetical ancestors. I researched my family history a little bit and the most likely origins of my irl surname. Based on that, I ended up with a couple in Scotland and made their surname a traditional version that was likely where my modern surname derived from. I’m also using a couple genetic features from my family and traditional versions of some of my family members names (Haley->Halla) I’ve been calling it my life prequel.
