"P Mapson"/Bathwick Hill House contacts?

"I am living on one of the frisian islands lying off the north coast of the
Netherlands.
The islands Vlieland, Terschelling and Ameland were liberated by members of
the 3rd Medium Regiment of the Royal Artillery.
Several members of this unit wrote their names in a Poetry Album of a young
girl on the isle of Terschelling.
Recently I obtained a copy of these pages.
One of the names mentioned is;

P. Mapson
Bathwick Hill House
Bathwick Hill
Bath
Somerset - England

I was wondering if mr. Mapson is still alive and living on this address, or
if there are relatives/ next of kin of mr. Mapson still living on Bathwick
Hill.
I would like to contact mr. Mapson or his relatives to exchange information.

Kind regards,

Dirk Bruin"

If anyone can help I will pass on details to Dirk.
