Percy was the third son of John and Lucy Ann Pashley (née Larder).
His father John was born in Hardwick near Worksop, in 1865 and his mother Lucy Ann was born in Donington, Lincolnshire, in 1866. They were married at Ordsall All Hallows on 28 May 1891 and had eight children who were all born in Bothamsall; the four eldest were baptised at Bothamsall Our Lady & St Peter. Their children were: George Arthur b. 1893, William (bap. William Henry) b. 1896, Percy b. 23 November 1897 bap. 13 February 1898, Ellen b. 1899, Joseph b. 1902, Sydney b. 1906, Eveline (Evelyn) b. 1908 and Harold b. 1913.
In 1901 John, an estates woodman, and Lucy were living on Cow Pasture Lane, Bothamsall, with their four children George (7), William (5), Percy (3) and Ellen (1).
They were still living in the village in 1911 but only six of their seven children were in the home on the night of the census: George, a butcher's apprentice, Percy a farm labourer, Ellen, Joseph (8), Sydney (5) and Evelyn (2). William was a general servant at Wellow, Nottinghamshire, in the household of Samuel Birkhead, a retired butcher and farmer, his wife, daughter and son who was a horse breaker. The youngest child, Harold, was born two years later.
John and Lucy were living on Main Street, Rampton, Nottinghamshire, in 1939 when the England & Wales Register was compiled; John had retired from work. Lucy died the following year and John probably died in 1949.
Two of Percy's brothers, George and William, also served in the war. George survived but William died in England in 1917 from wounds received in action. (See 'Extra information'). William was buried in Bothamsall churchyard as was George who died in 1961.
