Authorities also had been searching for a 6-year-old girl, but after talking to the owner of the home, they determined that the child hadn't been in the house when it was swept away after all, Franklin County Fire Chief Gary Watts said Saturday.
The boy, believed to be 5 or 6, was found dead Friday evening along Stony Creek, a normally a small stream that trickles through a bed of rocks about 50 feet wide.
Heavy rain Friday had flooded the creek, a tributary of the Kentucky River, sending water over a nearby bridge and washing out a roadway and several structures, including the home.
The woman's body was spotted by search crews in a helicopter less than a mile from where the home washed away, Watts said. Her name has not been released.
Roger Smith said he watched as the water swept the house away. He saw a woman at the window and rescuers trying to get to the home. But before the rescuers could get their boat off its trailer, the house slid away.
``The house was gone, Smith said. ``It took seconds.''
Franklin County, halfway between Lexington and Louisville, was the area hardest hit by violent thunderstorms that struck the central part of the state Friday afternoon.
Five to 6 inches of rain fell on Franklin County in 90 minutes, said James Brotherton, a National Weather Service meteorologist.
A county firefighter, was struck by lightning and was in stable condition at Frankfort Regional Medical Center.
High water stranded two school buses in the northern part of the county, said Stacy Floden, a spokeswoman for the state's Division of Emergency Management.
City fire crews responded and about a dozen students on one bus were taken to Bald Knob Fire Station about a mile away from Stony Creek and have been picked up by their parents, Frankfort fire Lt. Dan Shouse said. Four students on the second bus were taken home by the driver. There were no injuries to the students.
