Mr. Mortlock, you will always be a part of my best memories growing up in England. You and Miss Terry always had welcome smiles when I would come next door to see Joyce and Sheila. Rest in peace.

John was my 'adopted' father while I was stationed in Germany. He opened his house and took care of Dave, Ron and I. I will remember 'Dad' Mortlock very fondly for the rest of my life. Rest well John.
