Help Identify 2 trees

Hello,

I am looking to identify two trees I have in my backyard, they are both flowering and about 30 feet tall. I have attached 2 pictures one of each with its leaves and flowers.

Thanks in advance!

 

Wild Cherry(Prunus serotina?) and Robina (R. pseudoacacia?) species.

 

Black Cherry Prunus serotina and Black Locust Robina pseudoacacia.

 

Thanks alot I think you guys got it. the black locust tree it quite annoying with the root sucketing. I was considering getting rid of it but apparently it becomes a game of whack a mole if you do that.

thanks!
