PEAR...?!?!?!? Then you should soon have 'tiny' little fruits growing about the 'size of peas'. Unless of course conditions are right, and the trees were at least recently pruned and cared for properly :>)
Maybe you might get lucky and have some normal size pears sprout? The pear trees by me seem weak at the point where large branches attach to the trunk, and I've even seen trunks 'split' as well. Only after being heavily weighted down by 'ice' in a storm.
Stay well buddy...
This is one . I tought it was a dead olive tree , then it got leaves and flowers ..
