Cecil served with the Expeditionary Forces in Egypt from 1915 to 1918.
And although it is 100 years since that Great War, for Jill, the sacrifices of her grandfather and thousands of others is still raw today. "It's still real, what they did for us ... " she said. "I'll never forget what they sacrificed for us."
Cecil Anderson passed away in April 1954 and is buried in Dannevirke's World War I soldiers' cemetery.
Fortunately for Jill and her grandchildren, Hughin and Abbey Ross-Veale, her father had kept the family's war memorabilia safe in an old trunk and on Saturday they were able to wear the medals with pride.
"It means a hell of a lot to me to have these and pinning them on for Anzac Day is very emotional," Jill said.
"My dad, Eric, was a pilot officer and flight lieutenant in the Air Force and did a stint in Canada and West Africa as a rear gunner," she said.
Jill's grandson, Hughin Ross-Veale, wore Eric Anderson's World War II medals to the Anzac Day service, while his younger sister, Abbey had a set of miniatures of her great grandfather George Ross' World War II medals.
These included the Pacific Star, Defence medal, 1939 to 45 war medal and the New Zealand Service medal.
