More info:"Archaeologists have uncovered a trove of relics and remains at Chapel of St Morrell in Leicestershire. Some relationships last a lifetime -- and archaeologists have discovered that they can last even longer after unearthing two skeletons at a lost chapel in Leicestershire that have been holding hands for 700 years."

I found no information concerning the ages of the dead couples. Without a need to be converted into trees like the mythological Baucis and Philemon, I want to find a mindmate to grow old together, and it were an ideal to also die at the same time.
