Looks like there are no pear growers here, but there's a fruit and orchard forum linked below.

We had a very old pear tree in my last home, an old farmhouse that would be about 200 years old by now. It seemed to take care of itself and still produced pears.

Good luck with your trees.

Here is a link that might be useful: fruit forum
