Ms. Petty,
My grandparents, Lehman Ray Parrish and Louise Scott Parrish lived at 105 South East Avenue in neighborhood of Millville in Panama City. The store was on the lot where their house is (still) located. They closed the store and tore it down a few years after my father died.
They, along with my father, Bobby Ray Parrish are buried at Evergreen Memorial Gardens which is located off Highway 231.
I hope this helps.
