It wasn't his fault. Flinders died at age 40 in 1814, just one day after publishing "A Voyage to Terra Australis," a full account of his journey that included all of his maps. But when his sister-in-law came to visit his grave in 1852 at St. James Burial Ground, there was a problem: She couldn't find it. The headstone was missing. The churchyard had been remodeled. And according to archaeologists, a train station, Euston Station, had expanded into parts of the graveyard, making it virtually impossible for descendants, or anyone, to find the man who gave Australia its name.
