plant id? could it be Good King Henry?

Don't know what the following plant is, but once thought it to be Good King Henry.  Not so sure now.  The top photo is the mystery plant.....the bottom photo is standard lambsquarters along with a purple hybrid.  The mystery plant appears more shade-loving and comes on later in the summer as compared to lambsquarters which is quite early.  Location is north central plains of the US in the Red River Valley.  Thoughts?

It looks a lot like lamb's Quater. They're related so you may be right. I've never seen GKH.

I found a picture and I don't think the leaf edges look right.

Chenopodium album

Maybe white goosefoot?
