Context paragraphs:
Westmorland: Westmorland ( ; formerly also spelt "Westmoreland"; even older spellings are "Westmerland" and "Westmereland") is an area of North West England and one of the 39 historic counties of England.  It formed an administrative county from 1889 to 1974, when it was dissolved, after which the whole county was administered by the new administrative county of Cumbria.  In 2013, the Secretary of State for Communities and Local Government, Eric Pickles, formally recognised and acknowledged the continued existence of England's 39 historic counties, including Westmorland.

Scheduled Monuments in Powys: Powys is the largest administrative county in Wales.  With over a quarter of Wales's land area, covering much of the eastern half of the country, it is a county of remote uplands, low population and no coastline.  It was created in more or less its current form in 1974, and is the only one of the large county units created at that time to have been carried forward intact at the 1996 local government re-organisation.  It comprises three historic counties, namely Montgomeryshire, Radnorshire, and most of Brecknockshire.  There are 950 Scheduled monuments within the county.  This is far more than can be sensibly covered in one list, so each of the 3 historic counties is therefore listed separately, and each of these has two lists - one for the prehistoric sites and one for the Roman, medieval and post-medieval sites.

Association of British Counties: The Association of British Counties (ABC) is a non-party-political society formed in 1989 by television personality Russell Grant to promote the historic counties of the United Kingdom.  It argues that the historic counties are an important part of Britain's cultural heritage and as such should be preserved and promoted.  It also proposes that there be a clear official distinction between the historic counties and the administrative units known as counties—first described as a separate entity in the Local Government Act 1888.

Parliamentary representation by historic counties: The Parliamentary representation by historic counties is summarised in this article, with links to the articles about the representation of each of the historic counties in the House of Commons of the Parliaments of England (to 1707), Great Britain (1707-1800) and the United Kingdom (from 1801).

List of county seats in Georgia (U.S. state): The U.S. state of Georgia is divided into 159 counties, more than any other state except for Texas, which has 254 counties.  Under the Georgia State Constitution, all of its counties are granted home rule to deal with problems that are purely local in nature.  Each county has a county seat.  In Georgia, county seats typically have a courthouse at a town square.  Of the current 159 counties and two historic counties, 47 counties have changed their county seat at least once.

Former counties of Ontario: The Canadian province of Ontario has several historic counties, which are past census divisions that no longer exist today.  Most historic counties either merged with other counties, or became regional municipalities or single-tier municipalities.  Although counties had existed prior to 1849, after 1849 they replaced the district systems in administering local government and courts in Ontario.

Minor counties of English and Welsh cricket: The Minor Counties are the cricketing counties of England and Wales that are not afforded first-class status.  The game is administered by the Minor Counties Cricket Association which comes under the England and Wales Cricket Board (ECB).  There are currently twenty teams in minor county cricket: nineteen representing historic counties of England, plus the Wales Minor Counties Cricket Club.  Of the thirty-nine historic counties of England, seventeen have a first class county cricket team (the eighteenth first class county is Glamorgan in Wales), nineteen have a minor county team, while Huntingdonshire, Rutland, and Westmorland have neither, due to their small population.

County Tyrone: County Tyrone (from Irish: "Tír Eoghain" , meaning "land of Eoghan" ) is one of the six historic counties of Northern Ireland.  It is also one of the 32 traditional counties of Ireland and lies within the historic province of Ulster.  It is no longer used as an administrative division for local government but retains a strong identity in popular culture.

Historic counties of England: The historic counties of England were established for administration by the Normans, in most cases based on earlier kingdoms and shires established by the Anglo-Saxons and others.  They ceased to be used for administration with the creation of the administrative counties in 1889.  They are alternatively known as ancient counties or traditional counties.  Where they are not included among the modern counties of England they are also known as former counties.  Despite this name, several historic counties continue to be recognised as cultural regions and have their own county days, county flags and boundary signs, many of which were created or registered long after these counties were abandoned as units for administrative purposes.

Glencull: Glencull (from Irish: "Gleann Choill" , meaning "hazel glen" ) is a townland in County Tyrone, Northern Ireland.  It is situated in the historic barony of Dungannon Lower and the civil parish of Killeeshil and covers an area of 241 acres.
