I bought a foreclosed home this past February.
Hello and Welcome Suzy!
My guess is
I think mine look like your Lily #2 photo.
I live in Michigan too, and my mom has a flower bed full of lily of the valley that looks very similar to that. There were just a few when they moved in 10 years ago, and she likes them so has just let them go and they get fairly big.
I'm not a plant expert by any means though!
