Butternut would have been my guess a few years back. But having spent considerable time trying to learn some wood identification because of the access to many different kinds here and hand carving, my best guess now would be Catopa. It also is a pleasure to carve. Some often confuse it for walnut and it is used instead of walnut, because it grows so fast and stains well. It is native to yuour neck of the woods so maybe this was a local tree. Here is a link to a photo and I leave you to look up the rest.
