Lynn Crosby Gammill, co-founder of the Crosby Arboretum and a dedicated advocate for education, the arts, and Mississippi heritage, passed away at 88. Born in New Orleans on Sept. 13, 1936, she spent her early years in Crosby, Miss., before her family settled in Picayune.

A graduate of Sweet Briar College with a year abroad at the University of Paris, Lynn developed a deep love for French culture and a lifelong commitment to learning. After earning her teaching certificate at the University of Mississippi, she married Stewart Gammill III and raised her family in Hattiesburg, where she became a cornerstone of her community.

Lynn’s most notable contribution was founding the Crosby Arboretum, established in 1986 to honor her father, L.O. Crosby Jr., and provide an educational resource dedicated to native plants. Her work on the Arboretum’s board and her efforts to gather experts in horticulture and public gardens helped create a space that has become a lasting treasure for Picayune and beyond.

“Lynn Crosby Gammill’s vision and hard work brought the Crosby Arboretum to life,” said Mayor Jim Luke. “Her efforts have left an enduring mark on our community.”

In addition to her work with the Arboretum, Lynn’s influence extended across Mississippi through her involvement with numerous organizations, including the Mississippi Museum of Art and the Center for the Study of Southern Culture. She was also a Mount Vernon Ladies’ Association member, where she served as Mississippi’s Vice Regent for two decades.

Lynn is survived by her children, grandchildren, and extended family. A visitation will be held at Trinity Episcopal Church on Dec. 28, 2024, at 10 a.m., followed by a memorial service at 11 a.m. The family requests donations to one of the many charitable organizations she supported instead of flowers.
