Jim, who was 84, and Donna, 81, were among at least 24 people killed by the tornadoes, CBS affiliate WTVF reports.

According to an obituary written for the pair, they are survived by three children, four grandchildren and nine great-grandchildren. They moved to Mt. Juliet in 1977, joining First Baptist Church, according to the obituary posted by the Woodlaw-Roesch-Patton Funeral home.

For 43 years, they both taught many Sunday school classes and Jim served as a deacon. "They were a true example of God's love in their family, their marriage, the community of Mt. Juliet, and beyond," the obituary reads. "They were humble, kind and lived life fully. Whether they were on their daily walks, cheering on the Cincinnati Reds, Bunko or card night, church fellowship or supporting their children, grandchildren and great-grandchildren through any activity they exemplified the love of God."

Services for the couple will be held on Friday and Saturday. In lieu of flowers, the family asks that donations be made to First Baptist Church "to help with cleanup and restoration from the tornado," according to the obituary.

The tornadoes destroyed dozens of buildings and left about 50,000 customers without power, according to officials. The National Weather Service estimated that the tornado that hit the area was "at least" an EF-3, which indicates a "severe" tornado with 136- to 165-mile-an-hour winds.
