Please say a prayer for her. Love and Mercy Brian.”

“It is with a heavy heart that we let everyone know that our mom, Melinda Kay Ledbetter Wilson passed away peacefully this morning at home,” they wrote. “She was a force of nature and one of the strongest women you could come by. She was not only a model, our father’s savior, and a mother, she was a woman empowered by her spirit with a mission to better everyone she touched.”

Their statement continued, “We will miss her but cherish everything she has taught us. How to take care of the person next to you with out expecting anything in return, how to find beauty in the darkest of places, and how to live life as your truest self with honesty and pride. We love you mom. Give Grandma Rose and Pa our love.”
