John Dopping J.P., High Sheriff of Co Longford (1823) married in 1822 Frances,
daughter of Henry Cottingham of Summerville, Co Cavan and left amongst other issue
his eldest son and heir Ralph Dopping, who in 1858 married into the Hepenstal family.
John was an Irish scholar, a local historian and an acknowledged authority on the region
in which he lived. In the 1830s John O’Donovan, when in the area, consulted and quoted
him. While he may have been a scholar of some note, John was not at his best when
dealing with financial matters.
