Thomas Campbell was a Scottish poet. He was a founder and the first President of the Clarence Club and a co-founder of the Literary Association of the Friends of Poland; he was also one of the initiators of a plan to found what became University College London. In 1799 he wrote Pleasures of Hope, a traditional 18th-century didactic poem in heroic couplets. He also produced several patriotic war songs— "Ye Mariners of England", "The Soldier's Dream", "Hohenlinden" and, in 1801, The Battle of the Baltic, but was no less at home in delicate lyrics such as "At Love's Beginning".

Clan MacIver or Clan MacIvor, also known as Clan Iver, is a Scottish clan recognised by the Lord Lyon King of Arms. The clan, however, does not have a chief recognised by the Lord Lyon King of Arms. Because of this the clan can be considered an armigerous clan. The clan name of MacIver is of Gaelic origin, derived from an Old Norse personal name. Various forms of the surname MacIver, like MacGiver, are considered sept names of several historically large Scottish clans, such as clans Campbell and Mackenzie. There exists a Clan Iver society in Fife, Scotland.
