Thank you for livestreaming the lovely Vigil for Sr. Marlene this evening. I live in the Detroit area and was unable to make the drive to Adrian due to family commitments, but wanted to participate. I appreciate that you mad it possible via the livestream.
I am grateful to have worked with Marlene for over 20 years at St. Joseph's/ Henry Ford Macomb Hospital. The gospel reading for Marlene's Vigil tonight was well chosen, as she truly was a light for many others, including me. Marlene's simple lifestyle and generous positive spirit was an inspiration to me. What I will remember most was the positive encouragement she consistently offered in every day situations. I can hear her say "You did that well." It seems small, but offering your support in love is never small. Marlene, you did that well. And you will be missed dearly!

I grew up with Marlene (Sister Karen Marie) and her sister Beverly. From family gatherings to just going to school our lives were entwined. We were like family and my children called her Aunt Marlene. She was a sweet, smart caring person with a wonderful sense of humor! She will be missed.

Cemetery of the Adrian Dominican Sisters

Our Adrian Dominican cemetery with its circular headstones is a beautiful place of rest for women who gave their lives in service to God — and a peaceful place for contemplation and remembrance.
