The mystery of the trees

At the bottom of our back garden is a fence and on the other side of the fence is a strip of land between us and the playing field beyond. At one time there was a railway track there, long since gone, and there is a useful dog-walking path stretching for part of the way but there are also trees, a lot of tall, mature trees which, whilst useful for shade on hot, sunny days  and a perfect environment for birdlife and squirrels, are becoming a little too tall and prominent. Half our small garden is overhung by the branches and that, as well as the clay soil, probably explains why I can never get anything to grow here. Getting someone in to cut them back sufficiently to make a noticeable difference would probably cost an arm and a leg and  anyway, they are not our trees so the task should be someone else's responsibility.
With this in mind, I embarked on a search for the owners - fruitlessly, as it turned out. After much time on the phone and the internet, I discovered that this land does not belong to the local council, Arriva trains or British Rail but eventually I discovered that in 1960, the owner of the land had been one Mr R. Price.
And there the trail ran cold. Price is a very common name, especially in Wales and I couldn't track down a likely address.
So, if Mr R. Price. sometime of our area, is reading this, could I invite him to come and cut his trees back,
please........!
