Thank you all for your quick responses. Sumac seems like a good lead, however I can't find any tree/branch/leaf images (google) that really match up.
Interesting, the leaves are pinnate off the main leaf stem, but the leaf branches off the main branch are alternate pinnate in a spiral (?). The leaf branch cluster's overall shape is sort of tear-drop shaped.
What I don't want to do is plant this in my yard, then regret it because it is some known nuisance plant. Right now, the neighbors' is a pretty tree.

I believe Mountain Ash is sometimes used as a rootstock. I know for sure Mt Ash and pear are crossed - hybrid. I own one called Shipova.
Eric - The big one represents about 1Ã‚Â½-2 years of growth; it took off when the neighbor's Bradford Pear split and about 1/3 of the tree was lost. We have not seen any flower or fruit at all. Yet
. The smaller one is exactly the same plant, just came up in the spring. They are going to take it out, if I don't want it...
I took some more pictures, larger size below

Thank you - After looking at images of various "Tree of Heaven", I've ruled that one out because the leaf serration and branch configuration just doesn't match. However, I've seen plenty of those around here growing wild - especially out by the creek in our "back 40"
