Diane Wickett Christoff

Diane Wickett Christoff, 76 of Johns Island, South Carolina, passed away on Wednesday, September 23, 2026.

Born on June 24, 1950 in Phoenix, AZ, Diane was a daughter of the late Ruth Mildred (Mertz) Wickett and Floyd Jerome Wickett, Sr.

Not long after her birth, Diane and her parents returned to their hometown of St. Marys, PA where she was raised. She and her husband Jim and their family relocated to Memphis, TN from 1979 to 1989 and then to Cicero, NY from 1989 to 2015. While in upstate NY, Diane was an avid sailor and boater and spent countless weekends and summers exploring Lake Ontario and The Thousand Islands with lifelong friends. In 2015, she resigned from her 25-year position as an Office Manager for Benchmark Media Systems and retired to Johns Island, SC. She loved rural living, being close to nature, and the proximity to the ocean and beaches. She HATED static electricity!! She always had time for anyone who needed it and valued her relationships with people above all else.  Diane was covertly strategic and competitive in all family games and had a witty sense of humor. She will be forever loved, forever remembered, and forever missed.

Diane is preceded in death by her parents, Floyd Jerome and Ruth Mildred (Mertz) Wickett; her brother Floyd Wickett, Jr. (Patricia); and her sisters Carol Parisi and Laurie Long (Terry).

Diane is survived by her husband of 57 years, James Vollmer Christoff; son Broderick Christoff (Amber); daughter, Emily House (Rick); two grandchildren Mikayla Short (Nick) and Caleb House, two sisters Maryann Wickett and Lisa Salter (George); and numerous nieces and nephews.

A Catholic service is scheduled for November 11th at 11am at Holy Spirit Catholic Church, 3871 Betsy Kerrison Parkway, Johns Island, SC 29455. A catered on-site reception will follow the service.
