Nick Alley, 36, and two of his children have been identified as the three who went overboard and whose bodies have not been found from a boating accident in Polk County on Wednesday.
The children are seven-year-old Helana Alley and six-year-old Lazarus Alley.
Three other family members in the boat were able to swim to shore on the swollen Conasauga River a short distance from where it meets the Hiwassee River.
Several days of searching have not turned up the bodies.
The Mennonite family is from Delano in Polk County.
