Apparently it is caused by a fungus.
The internet is awesome - with Google I could diagnose the root cause, get inputs from strangers all across America, and find several options for fixing it. Oh, and we ordered the chemicals online, too.

The recipe and cost were easy to take. Some care needed to avoid contact.

Obviously the peaches are slow to loose their leaves this year.
The fungiside is easy to see.

Here you can see the withered leaves from summer.
Once the new leaves appear it is too late to treat them for the fungus, so we will hopefully get rid of it before spring.
