The Keyer has keyed Cobar for the location for the first group of names (although The Peak seems to be a legitimate location) and Clarence & Richmond for G Hardacre.
The header has been chosen if the location column has no clearly keyable place name and the fist column ignored.
My instinct was Cobar, The Peak for the first 4, then Cobar for the next two and Nana Creek for G Hardacre. And no &.
Am I correct?
