So sorry to hear of Marnie’s passing. I worked with Ken for many years. Liz and I had many lunches and or breakfasts with Ken and Marnie. They were a wonderful
couple. I know you have many wonderful memories that will help you through this difficult time.

Dear Patty, Bob and Brian and families, there are really no words that will help ease your heartbreak. You have lost a devoted mother, nana, and I have lost a best friend. We will have to take comfort that we will meet again on the other side. Until then rest in peace dear Marnie. Please accept our sincere condolences. Lindi and Mel Inch

I’m so sorry to hear of Marnie s passing. We loved our W.W. get together, lunches and phone calls. Will sure miss her.❤️

Our thoughts are with you during this time. Your mom was a treasure and loved by all of us. We are so happy and grateful that she came to Sioux Lookout the summer of 2017 and we got to spend some time with her. We all cherished that visit and I know that my mom really appreciated that visit and spoke about your mom often. Personally, when we lost Nana, your mom was like a surrogate Nana for me - they were so alike - your mom was loved by all who knew her. The world has lost a kind, compassionate woman today - so sorry for your loss.
Cindy, Keith and Joey Hunt

Marnie was an amazing lady. She was so warm and welcoming. My sympathy goes to all of the family members.
Lisa Zandbergen

My sincere condolences to your family. We had many good laughs around the fire pit at Warwick conservation park. Lot 101 Your family will be kept in my prayers.
