Multiply the father John’s age by his son John’s age:
Then add to this his son Joseph’s age:

There are marvellous views from the mausoleum as it is situated on the summit of Grey Mare Hill, 960ft (292.6m) above sea level, just to the east of the A68 road between Riding Mill and Castleside and 2½ miles (4km) from Whittonstall (parking area on the left as you turn off the A68). The elaborate domed mausoleum was built by Humphrey Hopper of Black Hedley in 1752 in memory of his wife Jane Hodgson, the Hoppers came from Scotland and the inscription records the presence of Nicholas Hopper here in 1573.
