Eighteen unmarked graves of veterans, at Launceston's Carr Villa Cemetery, now have headstones.
About 60 more headstones are yet to be put on graves.
This is part of the Headstone Project, which aims to recognise the service of WWI veterans and ensure they have their last resting place suitably marked.
Chairwoman Andrea Gerrard is calling for the families of 30 veterans to come forward.
"A lot of these people have no family left, we're looking at two and three generations on, and the family don't know about it or just don't know the history," she said.
Part of the project involves advertising the names of the veterans in the public notices, which will appear in The Examiner on Saturday.
"Sometimes we get some responses. We get a better response in Launceston than Hobart," she said.
"We had a couple of responses since the last one, got about three or four."
Seventy-six veterans at Carr Villa will be recognised once the project is complete, with more than 500 unmarked graves in the state.
Being able to contact the family is rewarding, Ms Gerrard said.
"Probably about 10 or 12 family members have been found. It's not many, but it's better than none," she said.
"They're usually really, really happy that something is being done. A lot of them say 'well what can we do or how can we help'. They're just so grateful that something is being done."
Many people are aware their family member is in an unmarked grave, but are unsure how to fix it.
"I don't think a lot of people understand, people out there say 'my grandfather is in an unmarked grave', but they honestly don't know how to go about making the first step," she said.
"Usually the first step is to go to the office at the cemetery, but usually for us, if it's a cemetery that we've already been working on, it's likely that we've already identified them and got them on the list."
The project started in 2011 and uses records to find out about the veteran.
"We usually have a dedication for them when they're finished and tell their stories and I put a death notice in the paper for them because a lot of people don't read the public notices," she said.
