On his KY death certificate, it looks like his name was originally written "Cora Collier", then someone went back over it and covered the 'a' in Cora, with a 'y'. They also wrote 'David' in front of the name so that it read 'David Cory Collier'. I don't know why this was done. As far as I know, his true full name was David Cora Collier.
