Fraxinus excelsior looks closest to me, there are different forms.

Where was it found, e.g. in woods, garden etc. The example in the photo is broken stems, did it come from a mature tree? Young Ash trees are fast growing which this specimen seems to show by the looks of the stem.
Fraxinus latifolia is the only native Ash in your location, but different ornamental forms of Fraxinus excelsior are sold.
