According to Wiltshire Folk Arts:

"Chris Wildridge has completed the transciption of all the Alfred Williams songs attributed to Wiltshire. He intends to make the transcripts available on the web together with appropriate tunes where they can be identified. We will endeavour to work alongside him in this fine body of information and add links and additional information as and where we can."

(my emphasis)

Sounds like there is yet more to come.
