Update: after reading this reply, I succumbed to the temptation to buy a marriage record.
Unfortunately, it shows there is no connection with the Bridget Hurley I was looking for when I posted that message. At least now I know.
Details from the certificate are as follows:
St Paul's C of E, Rockhampton, 20 Jan 1909.
Sam, William Yapp, bachelor, born Bundaberg, 25, parents Yapp Sam, miner, and Bertha Collard.
Hurley, Mary Bridget, widow, born Rockhampton, 23, parents Thomas Bowthorpe, miner, and Bridget Dwyer.
Following on from that, a quick scan of Qld BDM shows:
Nothing that appears to be a birth record for William, or any record for Bertha.
Mary Bowthorpe b 1885, parents Thomas Bowthorpe, Bridget Dwyer.
Mary Bridget Bowthorpe m John Thomas Hurley in 1907.
John Thomas Hurley d. 1908, parents Simon Hurley, Anne O'Rourke.
William and Mary Bridget Yepp appear on the census for Mt Chalmers until 1958 - William was a gold miner.
William Samuel Yeates (!) d 17/7/1964, parents Samuel, Bertha Collard.
Mary Yepps d 1972, parents Thomas Bowthorpe, Bridget Dwyer.
Yap Sam d 05/07/1885, parents Nelson Collard, Louisa Ash (probable this is Bertha).
Yap Sam Yap Sam d 10/01/1901 father Yap Sam. Connection?
Hope this helps.
