Two more pics

It could be an ash.

The top picture looked like an Arizona ash to me, but somehow the leaves don't look right. Compare the leaves to these:

Arizona ash tree leaves

Or perhaps get a better focused photo of the leaves. The leaves will tell you a lot in their size, shape, veining, edges, color, placement, shininess, etc.

It might be an Anacua tree. The leaf photos are a bit blurry, do they have a rather rough surface? Compare it to photos here: Anacua tree

Hard to tell, but could be Arizona ash. Not a Texas Ash.
