Yes!! I think we can trace "Dick" to Australia.
A tree on Ancestry has Richard Henry Williams b 1907 son of Richard Henry Williams/Charlotte Dutton marrying a Mary Ellen O'Connor in Queensland in 1929 and dying in NSW on Christmas Eve 1969.
Don't rely on other detail in that tree, which looks rather confused as to dates and places on the English side of things

. And they give him an additional middle name of Llewellyn for which the source is not clear.
BUT they do attach an image of the 1929 Queensland marriage certificate showing the groom as Richard Henry Williams, 21, a cook, parents Richard Henry (engineer) and Charlotte nee Dutton. All very promising.
