From post #8, the header in the burial register reads 'Burials in the Burial Ground at FINCHLEY, for the Parish of St. Mary, Islington . . . in the Year 1880'
In 1854 (according to Wikipedia) the St Pancras Burial Board bought 88 acres of land on Finchley Common, for use as a burial ground. The cemetery was extended in 1877. Many thousands of people from the boroughs of Islington and St Pancras/Camden are buried there:
