Seriously consider having it professionally removed - and the stump dug out (not ground down). Have all the pieces carted away intact - don't chip it. Even the sawdust can cause allergic reactions.
The allergen in poison ivy, poison oak, and poison sumac is the same, so if you are sensitive to one, you are sensitive to all.
Those who are particulary allergic may wish to have it bulldozed out rather than risk contact with the sawdust from felling.
Of course, before going to that expense, I'd want to have the tree more positively identified than me looking in a library book.
If you are not allergic, or only mildly so, you can cut it down yourself. Just wear protective clothing and wash it (and yourself) thoroughly afterwards. As pointed out already, the risk will be less if you cut it while the tree is dormant (wintertime). There are more concentrated versions of Roundup available - usually labeled as "brushkill" - that you can paint on the stump to kill it.
Be careful, and good luck.
