Hey, does anybody know what this tree seedling is?

I found this yesturday growing under a birch in my yard at the bottom of my driveway. Theres some a bit larger just like this growing under the same birch. I thought they were suckers growing from the birch tree and I found this one yesturday and pulled it up thinking it was a birch seedling off the birch. The leaves have kind of a ruff feel to them and I’m not sure if birch leaves have that feel to them.

is this a river birch or some kind of a elm? thanks.
