I too, am bummed over the disappearance of the Butler DNA History site. I used it quite often to eliminate other Butler families, and observe their history and location.
I wrote to Billie Sutton and she too is baffled and bummed.
It has been apparent for some time that the overseer had no interest, but when he asked for funds Billie and I both contributed. I would urge any Butler to add their genealogy to FTDNA if they were tested there. Butler genealogy needs to be preserved for future DNA contributors.
