Tree Looks Like Mountain-Ash with Different Leaves

I have a tree in my front yard that has berries that closely resemble those of mountain-ash but the leaves are wrong; I don't know what the leaf shape is called, the leaves are small and light-to-dark green. It has flowers in spring that are somewhat broader and less lacy-looking than the mountain-ash, but otherwise similar.

 

Of the leaves? Sorry, it's deciduous. But I have one or two of the berries.

 

Here's the photo:

I'm no good at ID-ing trees without leaves. There are a couple of hundred different types of mountain ash, try to google "Sorbus" and have a closer look at the photos.

 

It resembles Sorbus aria, but the flowers are less delicate-looking than Sorbus aria and my tree's leaves are somewhat smaller and vaguely heart-shaped.

 

I think it might be hawthorn. Would this be a possibility? Its flowers resemble hawthorn and, to some extent, the leaves.

 

More like Crataegus mollis (Downy Hawthorn) leaves than like the leaves in the picture you linked to.
