Early life and training
Park Cottage, Sandiway, the birthplace of John Douglas
John Douglas was born at Park Cottage,
Sandiway, Cheshire, on 11 April 1830 and baptised on 16 May 1830 at
St Mary's Church, Weaverham.
 He was the second of the four children, and the only son, of John Douglas and his wife Mary née Swindley (1792–1863). John Douglas senior was born in
Northampton about 1798–1800 and his wife was born in
Aldford, a village on the
Eaton estate in Cheshire; her father was the village
Eccleston, another village in the Eaton estate. John Douglas senior was by trade a builder and
joiner, and also described himself as a
surveyor and a timber merchant. In 1835 he acted as architect for a house at
Hartford, a village between Sandiway and
Northwich. At the time of the
1851 census he was employing 48 men. He owned land in Sandiway, and a house and land in the neighbouring village of
Nothing is known of John Douglas junior's school education. He gained knowledge and experience in his father's building yard and workshop which were attached to the family house. In the mid or late 1840s he was
E. G. Paley, of
Sharpe and Paley, architects in
Lancaster, Lancashire. When his articles were completed, Douglas became Paley's chief assistant. In either 1855 or 1860 he established his own office at No. 6 Abbey Square, Chester.
Family and personal life
Douglas's elder sister, Elizabeth, was born in 1827. His younger sisters were Mary Hannah and Emma, who were born in 1832 and 1834 respectively. Mary Hannah died five months before Emma's birth, and Emma herself died in 1848.
 Douglas married Elizabeth Edmunds, a farmer's daughter from
Flintshire, on 25 January 1860 in
St Dunawd's Church in the village, a church he was later to restore. Initially the couple lived over the office at 6 Abbey Square, and later they moved next door to No. 4. Their five children were born in these houses, John Percy in 1861, Colin Edmunds in 1864, Mary Elizabeth in 1866, Sholto Theodore the following year, and Jerome in 1869. Only two of the children survived to adulthood; Mary Elizabeth died from
scarlet fever in 1868, Jerome lived for only a few days, and John Percy died aged 12 in 1873.
About 1876 the family moved to live at
31 and 33 Dee Banks, Chester, one of a pair of semi-detached houses overlooking the
River Dee, which were built by Douglas. His wife died in 1878 from
laryngitis after a year's illness. Douglas did not remarry. His son Colin trained as an architect and worked in Douglas's office but died in 1887 at the age of 23 from
consumption. His other son Sholto is not known to have had any profession but he was a heavy drinker of alcohol. During the 1890s Douglas built a large house for himself,
Walmoor Hill, also at Dee Banks overlooking the river. Here he lived until his death on 23 May 1911 at the age of 81. His funeral was held at
Overleigh old cemetery, Chester, where he was buried. The following Sunday a memorial service was held at
St John the Evangelist's Church, Sandiway. His
estate amounted to a little over £32,000 (equivalent to £2,990,000 in 2016).
 Apart from his surviving buildings, only two memorials remain to his memory. One is a tablet in
St Paul's Church, Boughton, the church in which he worshipped and which he had rebuilt.
 The other is a plaque placed on one of his
buildings in St Werburgh Street, Chester, in 1923 by his pupils and assistants.
