Diane has been a good friend for over fifty years. We have shared many wonderful times together as our families grew up together. Diane was a woman of great faith and was always positive in her outlook even when things looked bleak. She fought a fine fight and now is resting until Jehovah calls her out of her sleep. We will miss her smile and her sense of humour. May Jehovah wrap his loving arms around her family as they mourn her loss. Revelation 21:4.

My fondest memories were back in the summer of 1972 when I first met Diane and Dave and developed a great friendship. I will always remember Diane curling up her fingers in front her and giving that sweet mischievous grin and chuckle. We will miss her.
David, you are in my prayers buddy. Soon this old system will be a thing of the past and we will be able to welcome back those we have lost. May Jehovah keep you strong.
My sincere condolences David, to you and your family. Bob

Diane was my bridesmaid over 45 years ago. She was my best friend and I'll miss her so much. How I look forward to seeing her again in Paradise on earth, whole and without pain. My heartfelt condolences to David, Diane's boys and grandkids, and extended family. I miss her.

I would indeed like express my appreciation to Dr. Crabtree and all the medical personnel her friends and family that assisted and ultimately allowed my mother to fight the long and most courageous fight imaginable in her battle with cancer. An immense thank you also to my father who did such an admirable job assisting and caring for my mother for all those years as she struggled to stay ahead of it and standing right beside her. It was no doubt her faith, her friends and the love and support for just a couple months short of 50 yrs...., of a loving husband, that gave her as much time as she had to remain with us.
