Note in this photo of an elm leaf how the base of the leaf is uneven; one side is larger than the other. That is always indicative of an elm. My guess is your tree is either a chestnut or one of several different oaks such as Sawtooth Oak or Chinkapin Oak.

If I could see a clean cross section cut of the branch, I could tell in a second if it was an oak. The rays that make for the shiny plates on quarter sawn red and white oak show up very well.

Oak rays -

The result of milling these rays on a tangent -

P.S. Ash looks similar to oak, but does not have these rays.
