Debbie, Leo, and Joan,
Our condolences to you on the loss of your mother. Mothers are special people.
She was the last surviver of Grandpa(Frank) & Grandma(Helen) Seiffert’s sons, daughters and their spouses – Bill & Marcella, Margaret & Gene, Lee & Norm, and Leo & Mary Lu.
Without all of them, many of us would not be here.
Im so sorry for the loss of your Mom & Grandma. It is so hard to lose the matriarch of a family. So many have been here in circumstance but all I can say is she will be forever in your memory & heart forever! Love to you all, Marie Dill💔
So sorry for the loss of your Mother. Leo, I know how much time you spent helping her do enjoyable activities in the years prior to her passing. I know you will miss the weekly hair appointments, eating out afterwards, and spending time showing your love. I’m proud of the way you stepped up, to shop for her food. You showed her your love and I’m sure she was grateful that you were her son when it meant the most. So sorry for your loss. Her memory will go on especially in your heart. On a final note, I really enjoyed getting to know her and spend Thanksgiving Dinners with your whole family. I live in Colorado, but if I was closer, I would be at the service and funeral. Sincerely, Carla
