Marion Historical Museum director Peggy Blackman presented Gracie Mackey a “world’s best volunteer” certificate Monday for volunteering her services to the museum every Friday throughout the summer.

Mackey, who attends Marion Middle School, said she had a lot of free time after swim team, so she stopped by the museum and asked Blackman whether she could volunteer to help over summer break.

“Gracie is an enthusiastic young lady who has helped me with so many things,” Blackman said.

The experience has proved educational.

“I have learned so much more about history by helping,” Gracie said. “I have had to read more into the details and help sort pictures. I’ve enjoyed it.”
