I have a feeling it might be called May or something like that

I need to see some complete leaves to judge Jenny.
The Flowers do look like 'May' real name Hawthorne. It will have sharp thorns if it is.
The leaves when fresh and young can be eaten, we used to call them 'Bread and Cheese'
Generally they are white, at times with a faint pink edgeto some of the petals, there is a cultivated variety with red flowers.
The common bush is often used to create field bounderies or hedge rows.
May or Hawthorne in Autumn.

I do not think your tree is one, the leves are wrong.

Thank you so much for trying to find out what this tree is called. It doesn't have berries like your picture, so I think we're still in the dark about this one

I did send another photo of 'Spirea' it could be what you have.
