I do believe you are looking at Ailanthus, or Tree of Heaven, which is pretty much the opposite of where that tree came from. It’s an invasive from Asia, and the favorite food of the Spotted Lanternfly, a fact everyone in the southeast corner of Pennsylvania has recently become well aware.

Yeah...it is Ailanthus. Seed pods confirm that. Another name is stinking sumac....but it is not a sumac...but it does stink! Take a whiff - once you know that, it is the easiest way to confirm another if you are ever in doubt.
Ideally, it gets herbicide BEFORE you cut it down to prevent root suckering. If that is not an option, get triclopyr (Garlon) or picloram (Tordon) on the fresh cut stump as soon as you make that last cut. I'll leave the stump a foot or two high until we are done cleaning up, then make a last cut and treat it right away. If you try to treat a stump that was cut more than 20-30 minutes ago, it will be useless.
Cut stump would need triclopyr 3a (amine formulation), not triclopyr 4 (esther formulation). Consumers at home improvement stores usually get amine formulation at 7%, which is low concentration for cut stump, so you may have to retreat sucker sprouts.

Triclopyr 4 in an oil carrier is very effective cut stump treatment - especially if you get some around the sides to go through the bark.
That is what I have seen the most recommended for pre-cutting treatment.
Mix a little imazapyr in there if you really want to punch it...but that stuff can move in the soil.

I had no idea it suckered that badly from the stump. I don't know much about tree of heaven.. were they planted for a time before they were considered invasives?

They were not widely planted...but yes people planted them on purpose.
The problem isn't coming off of the stump (coppice sprouting), but rather the root suckering. If you cut down the main tree, the roots will send up suckers all over the place throughout your yard and all of the neighbors' yards as well.

I believe the staghorn sumac looks like Aailanthus they may be in the same family but they definitely don't smell the same
Some kind of salix is my guess.

Just to be a total nerd-
The reference to Heaven is a translation from the Latin species name ‘altissima’ (“The Highest”). It’s referring to the growth rate and height, not its (limited) qualities!!
My guess is African Sumac.

I didn't even look that up on your first post because those first pics are Ailanthus. Then after this clarification post, I looked it up...yeah, what @Amber Jones posted certainly does look like African sumac to me!
