Great post newcomer! I’m not confirming your wood but these guys’ll get ya squared away. Welcome to the ranks.
wood is a bright yellow when splitting. there never were any hedge apples on the ground, and i don't think i have ever seen any mulberries.
I'm not at all familiar with either wood that others have said, so I'll leave it to the regional experts. A big welcome to you johnnyboy , from another John. Lots of great conversation, information, great folks here. Enjoy!
The only Mulberry tree I ever saw in my life turned the road under it reddish purple from all the squished berries by cars.
The big problem is that the birds eat the berries and “drop” them on your laundry on the clothesline, usually on your white sheets. I think there are male and female Mulberry trees and the females have fruit. My aunt had a huge Mulberry tree and she made the best pies with those berries.
