Hello,
I myself have started a naval war search on my late father,If you have a naval number and/or as much information, Write to Ms Kate Tildesley,Curator.
NAVAL HISTORICAL BRANCH (NAVAL STAFF) Ministry of Defence HM Naval Base,Portsmouth,Hants,PO1 3LU England, It was very fruitfull for me as I was given his full navy record with dates.
My father was on board hm Weston which I beleive was sent to escort HM Auxiliary Minelayer Princess Victoria Operation ID Mining,I dont know if this is the same ship,however If your grandfather has any information I would be most gratefull for return as I am trying to fit a nice portfollio to gether for my sisters 60th birthday present in March.
Kates phone number is 02392724893. I wish you well.
Regards Laura
