IIRC, the farm family with the critters assaulting their house was a fairly discrete incident involving just that family. The Flatwoods case was much bigger involving more people.
This is the one I was thinking of...

“Soon, strange things began to occur. The family dogs began to bark outside. The man of the house, “Lucky” along with Billy Ray went outside to see what the problem was. They were both stunned when they saw a three to four foot tall creature, making its way toward them with its hands up. They two men described the creature as like nothing they had ever seen before. It had large eyes, long thin mouth, thin, short legs, large ears, and its hand ended with claws. Billy Ray fired his .22 caliber rifle, and Lucky fired his shotgun. The barrage of bullets had no effect on the being.”
