Dear Gerry,
We missed this the first time we read it. There was such an unexpectedly large response to our original post.
Can you check the date of this entry. This entry in the directory would be the last sighting of William, and back in Melbourne at a different address, rather than in Bendigo. This seems like a major breakthrough for us! This is definitely him as he was William Clark Atchinson.
