At the Katoomba Anzac ceremony on Saturday, a separate roll call was made of World War One veterans with Mountains connections.
As their names were called, their relatives laid wreaths in their honour.
Katoomba sub-branch president Brigitte Moseley had advertised in the Gazette in February for personal stories from locals whose relatives had served in Gallipoli or the Western Front.
The Diggers' names, enlistment dates and battalions were read out to the crowd as the wreaths were laid.
Katoomba resident Sue Emonson remembered her grandfather, Allen, as well as two great-uncles Percy Emonson, who died in France, and Sgt David John Anderson who died at Gallipoli, aged just 18.
Also honouring ancestors were Laurel Simmonds, from Brisbane, and Chris Rush, from Bilpin. They were commemorating their great uncle Percy Tuck, a former officer in charge of Katoomba Fire Station, as well as another great uncle, his cousin Albert Tuck.
In all, 12 members of their family served, Ms Simmonds said.
"Our great grandparents sent 12 grandsons to the war. Only seven came home," she said. "Three were killed in Gallipoli and three in France. Can you imagine waving off all your grandchildren and five not coming back?"
Ms Simmonds said Percy Tuck's remains had been among the soldiers exhumed from graves in Fromelles and later identified, in his case through the DNA of a cousin in Victoria.
She was there in 2013 at a dedication ceremony honouring the men, who now had names.
"It was one of the most amazing things I've ever done," she said.
She and Mr Rush did not know each other until Ms Simmonds began to research her family's war history. "It was the boys' spirit they brought us together," she said.
The two were delighted to be back in great-uncle Percy's old stomping ground to honour his memory.
