Tree in SE Texas - Leaves Change Colors in Fall

Hi everyone.
Mrs. E has this tree to put in the plant sale, but she doesn't remember it's name.
It grows around here (SE Texas zone 8-9). She says the leaves change colors in the fall... mostly at the top and think it might even put on little blooms just before the change. She had one that was pretty tall... maybe 20+ feet?
Any idea of what this is?
Thanks in advance and sorry I don't have any more info about it.

The leaves look like a sumac. They turn red in the fall and a sumac does have a flower also.

 

Thanks Chrisle.
I'm going to print out a couple of photos and let her see if that's what it looks like.
