Clan Nicolson is a Lowland Scottish clan.
 The clan claims descent from an Edinburgh lawyer who lived in the 16th century and from a distinguished line of Aberdeen merchants who preceded him.
 During the mid-1980s David Nicolson, 4th Baron Carnock was recognised by the Lord Lyon King of Arms as the chief of Clan Nicolson.
 Around the same time, a Nicolson who claimed descent from the Highland clan of "Nicolsons" historically centred on Skye, petitioned the Lord Lyon King of Arms to be recognised as chief of his own clan.
 The Lord Lyon King of Arms accepted this man's petition on the condition he took the surname "MacNeacail".
 In consequence there are two Scottish clans with similar names—the lowland Clan Nicolson and the highland Clan MacNeacail.

The Ulster Scots (Ulster-Scots: "Ulstèr-Scotch"), also called Ulster-Scots people (Ulster-Scots: "Ulstèr-Scotch fowk") or, outside the British Isles, Scots-Irish (Ulster-Scots: "Scotch-Airisch"), are an ethnic group in Ireland, found mostly in the Ulster region and to a lesser extent in the rest of Ireland.
 Their ancestors were mostly Protestant Lowland Scottish migrants, the largest numbers coming from Galloway, Lanarkshire, Renfrewshire, Ayrshire and the Scottish Borders, with others coming from further north in the Scottish Lowlands and, to a much lesser extent, from the Highlands.
Ulster Protestants (Irish: "Protastúnaigh Uladh" ) are an ethnoreligious group in the Irish province of Ulster, where they make up about 43% of the population.
 Many Ulster Protestants are descendants of the Protestant settlers involved in the early 17th century Ulster Plantation, which introduced the first significant numbers of Protestants into the west and centre of the province.
 These settlers were mostly Lowland Scottish and Northern English people and predominantly from Galloway, the Scottish Borders and Northumberland.
Guth na Bliadhna was a Scottish Gaelic and English-language magazine published between 1904 and 1925 in Glasgow.
 It was known for its focus on politics, particularly issues radical at the time such as Scottish independence and even the political union of Ireland, Scotland, and other Celtic-language speaking areas.
 The magazine was established by a Roman Catholic, Ruaraidh Arascain is Mhàirr, a Lowland Scottish aristocrat who had learned Gaelic from a nurse.
 The next long-running Gaelic periodical would be Gairm, first published in 1952.

 For the five centuries following Sir Alexander, the Cockburn family was, through its significant landholdings and political connections, an influential force in Scottish affairs.
The Ulster-Scots Heritage Council (USHC; Ulster-Scots: "Ulstèr-Scotch Heirskip Cooncil") was established in 1995 as an umbrella organisation to represent the Ulster Scots community.
