Question: The M25 motorway marks the western boundary of Coinbrook, Berkshire with which London village that may also be considered a hamlet?
Context: West Byfleet is a village in Surrey which grew up around its relatively minor stop on the London & South Western Railway: the station, originally "Byfleet and Woodham", opened in 1887.  More than 1 mi from the medieval village of Byfleet, the initial concentration of a new development soon established its own economy apart from that of a dependent London commuter village and spread in most directions to its borders including to the border of the old settlement, divided by the shielded London Orbital motorway today.  The first place of worship was dedicated in 1912, the parish of West Byfleet associated with it was established in 1917.  The village is bounded to the north by the Basingstoke Canal and to the east by the M25 and the Wey Navigation Canal.  Forming part of the contiguous development centred on London and its 'stockbroker belt' just outside the M25 motorway, it is 8 miles from London Heathrow and equidistant between the business parks of Woking and Brooklands.  In local government it forms a ward on the same basis as its parish in the Borough of Woking. Well Hill is a small relatively rural settlement, a large hamlet or possibly a small village, in the Sevenoaks district of Kent.  It lies immediately east of the Greater London border, is 16 mi southeast of Charing Cross, London, and is within and very close to the M25 motorway.  The hamlet is in the Kent, Sevenoaks District, but is close to Chelsfield and other parts of outer Orpington, in the London Borough of Bromley; Orpington is also the post town. It is in the civil parish of Shoreham The M25 or London Orbital Motorway is a 117 mi motorway that encircles almost all of Greater London, England (with the exception of North Ockendon), in the United Kingdom.  An ambitious concept to build four concentric ring roads around London was first mooted in the 1960s.  A few sections of the outer two rings were constructed in the early 1970s, but the plan was abandoned and the sections were later integrated to form a single ring which became the M25, aka London Ring Road, finally completed in 1986. Eagleby is a suburb of Logan City in Queensland, Australia located on the southern bank of the Logan River at the juncture with the Albert which forms the southern and eastern boundary.  The Pacific Motorway marks the western boundary.  Eagleby is northeast of Beenleigh, and was originally a suburb of Beenleigh. Maple Cross is a village in Hertfordshire, England, which up until the Second World War consisted of an inn, a blacksmith's shop and a few cottages.  Today there are around 800 postwar council houses.  Some of these have been sold into private ownership.  The area is close by junction 17 of the M25 motorway, which makes up the western boundary of the village.  It lies on the western fringe of Rickmansworth, about 8 km west of Watford and 6 miles north of Uxbridge.  It is in the civil parish of Maple Cross and Mill End. Noak Hill is a village in the London Borough of Havering.  The locality is 17.1 miles northeast of Charing Cross.  It is situated on hilly terrain in the far northeastern edge of Greater London with the M25 motorway being the boundary.  The village consists of various period homes, many of which are listed buildings, a 19th-century church and scattered farms.  It forms part of the Romford post town.  It is located immediately north of the post-war estate of Harold Hill and east of Havering-atte-Bower.  Noak Hill was a ward in the ancient parish of Hornchurch.  By the 16th century it had come under the control of the Romford vestry and was included in the newly created Romford civil parish in 1849.  From 1895 Noak Hill became a separate civil parish and had its own parish council until 1934. Ebbsfleet International railway station is a railway station in Ebbsfleet Valley, in the Borough of Dartford, Kent, 10 mi outside the eastern boundary of Greater London, England.  It is near Dartford and the Bluewater shopping centre to the west and Gravesend to the east.  The station is part of the Thames Gateway urban regeneration, a project of national priority.  It stands on the High Speed 1 rail line, around 400 m south-west of Northfleet railway station and the Stonebridge Road area of Northfleet.  The station lies off the A2 trunk road, about 5 mi from its junction with the M25 motorway.  During the London 2012 Olympics, it served as a primary park-and-rail service as it is very close to the M25 motorway, allowing easy access for over 10 million commuters. Longford is a village that has never had a church so can also be considered a hamlet, immediately north-west of London Heathrow Airport in the London Borough of Hillingdon, formerly part of Harmondsworth by tithes, land tax, vestry and still by Church of England parish.  Its historic county is Middlesex.  Longford is 15.8 miles (25.4 km) west of Charing Cross and within the M25 motorway which marks its western boundary with Colnbrook, Berkshire. Antoni Imiela (born 1954) is a convicted British rapist who grew up in County Durham, England.  He was found guilty of the rape of nine women and girls, and the indecent assault, and attempted rape, of a 10-year-old girl whom he repeatedly punched and throttled.

Byfleet is a village of medieval origin.  Byfleet takes up the far east of the borough of Woking and much of the land is within the widest gap between the Wey Navigation and the River Wey, a tributary of the Thames.  Its western boundary is the M25 motorway – it lies within the orbital motorway of London and its northern extreme takes in most of Brooklands business, hotel, museum and retail estate between Byfleet and New Haw and the more major Weybridge railway station on the South Western Main Line.
