Betstyle. The parent chapelry was upgraded with a church in 1862 and installed with stained glass windows in 1865 by D.G. Rossetti by which date it had many isolated streets of housing to serve such as around the crossroads at Betstyle (also written as Betstile). West parts from 1409 until the 20th century were frequently referred to in title deeds as Colney Hatch. Development was tightly constrained. It was estimated the hamlet had 12 of 78 taxable houses in the narrow parish in 1795; but 33 inhabited houses in Colney Hatch are recorded in 1801. This co-parent parish extended a total of west, Friern Barnet. Maps show the name Colney Hatch, interchangeably with New Southgate, coming to cover the more developed hamlet Betstyle, in the chapelry of Southgate within the parish of Edmonton; the refined hamlet and grand asylum outweighed the initial stigma in official maps and deeds, but less so in social organisations and in the naming of the railway station, the line of which resembles the historic split between the two parishes and later districts including today's boroughs. The crossroads of Colney Hatch had Halliwick manor house standing north of some cottages on the south-west corner; The White House and The Orange Tree Inn on the north-west side near to Brook House; The Priory, north-east with Woodlands, Greenbank, and Springfield to the north to which were added the Hermitage and several cottages on the south-west corner by 1783. It saw very little change in the 19th century before the construction of the county lunatic asylum: in 1882 Colney Hatch was described "as a village which had sprung up to serve the staff". However Colney Hatch was from 1851 slowly erased from the names of schools, churches and most other organisations as residents sought to distance themselves from a lingering social stigma from passers-by and social gossip across the county of the large mental health institution. The vast site operated for many decades, first under an enforced mass segregation regime which was later abolished nationwide, to treat the mentally unwell — Colney Hatch Lunatic Asylum. All 19th century urban development was concentrated in the east on what had been Betstyle, from the rural centre of the ancient, that is to say medieval-founded, elongated parish of Friern Barnet to the northwest. The name Colney Hatch Park was used by some developers for this area; however the new name New Southgate
