The accomplishments of James Spiers Freeman while living in Dannevirke will be the focus of Sunday's tour of the Dannevirke Settlers' Cemetery.
The large headstone, which is on a tilt, marks the graves of not just James Freeman but eight members of his extended family.
Freeman is thought to have bought a number of adjacent plots.
Tour co-ordinator Sharyn Burling has been researching Freeman's life in Dannevirke.
"At this point I don't know whose name is on the headstone. I will need to use some cunning ploys to make the lettering legible without damaging the stone."
