Family and friends paid their last respects to Sean Fowler, 44, Terri Tucker, 31, and Tyler Tucker, 8.
A visitation ceremony was held at Nowell Funeral Home.
The family then traveled on a procession down Highway 14 West to Whitehall United Methodist Church.
Seven other victims also died when the EF-4 tornado struck Louisville.
The tornado is the second deadliest in the state since 2000, topped only by the April 27th tornado that devastated Smithville in 2011.
