On September 10, 1948, two skeletons were discovered while trying to make a foundation for a tennis court in Abergavenny, Wales. One of the skulls was first discovered, and the rest of the remains were found 2 feet below the surface. There was no evidence of this being a designated place for burial. The way the bones were found made it obvious that the two were buried as bodies and not as bones buried at a later time. The two were believed to have died no less than 10 to 15 years before, but it's also possible that they had been dead for hundreds of years.
The adult skeleton was believed to be a man between 40 to 70 years old.
The child was around 7 years old.
