I can remember going to Bert’s yard sales with my Nanny and Pappaw when I was just a little girl. Bert was always so kind, and had such a good nature. I will keep her family and friends in my prayers. May God touch you all with his healing hands, and comfort you during this tragic time. Rip Bert.

Roberta was a special friend who always had a hug for me! We shared 2 great grandsons, Lucas and Landen. We were welcomed in her home for gatherings, especially, Christmas Eve. All the children even those who weren’t related received presents. Roberta was a very kind and giving person. We will miss her! Prayers for Jason, Valorie & children, Lori & Samantha, Kathy and the rest of the family I didn’t mention. ❤️
