Hi Lin,
Thank you for checking. You're right that the foliage isn't right for Hedge parsley. When I was looking for pics of prairie bishop, I discovered that Ladybird Johnson Wildflower org shows two pics, one looks like hedge parsley (definitely incorrect image) and the other looks much like mine but my flowers aren't so tight together...

my foliage is more dill-like but has a sweeter scent. It's a spring flower so I may have to wait to get more info.
