Supposing you should spot something other than cupmarks carved into the stone:
Long Tenure. – The following tenure on the Earl of Haddington’s estate in East Lothian may vie with that on any nobleman or gentleman’s property in the country.
Mr John Dudgeon, present tenant of Easter Broomhouse, near Dunbar, in the year 1769, carved his name on a monumental stone on that farm. Under the noble family of Haddington, Mr Dudgeon’s father and grandfather were successively tenants of Easter Broomhouse, neither of whom were short-lived. We know that Mr Dudgeon, who is now considerably upwards of eighty years of age, is in excellent health, and has a second time, in 1839, carved his name on the same stone as tenant of the farm. – Edinburgh Courant.
