"Archaeologists discovered the sarcophagus at Mangotsfield, near Bristol, while examining a former school playing field before the bulldozers moved in. The find is regarded as one of the most important Roman discoveries in the region." Source: The Independent (1997).
"Experts from the Avon Archaeological Unit believe the skeleton, which has been nicknamed Titus, belongs to an important Roman official who was able to afford a lavish burial. They hope the find could lead them to the site of a nearby Roman villa."
Note: I'm not sure if they ever discovered the villa they were looking for, but a really spectacular villa, one of the largest ever found in the UK, was unearthed near the village of Tilbury in Wiltshire earlier this year. I'm pretty sure that Tilbury and Bristol are on opposite sides of the country, so the finds don't have anything to do with each other, but I just thought I'd mention it. If "Titus," the Mangotsfield skeleton, was an important Roman official, it seems likely that his estates were located near his burial site.
