Torquil is an Anglicised form of the Norwegian and Swedish masculine name Torkel, and the Scottish Gaelic name Torcall. The Scottish Gaelic name Torcall is a Gaelicised form of the Old Norse name Þorketill. The Scandinavian Torkel is a contracted form of the Old Norse Þorketill. This Old Norse name is made up of the two elements: Þorr, meaning " Thor" the Norse god of thunder; and ketill, meaning "(sacrificial) cauldron".
Scandinavian variants of the Torkel include: the Norwegian and Swedish Torkil, Thorkel; the Norwegian Torkjell; and the Danish Torkil, Torkild.
A variant spelling of the Scottish Gaelic Torcall is Torcull.
A similar Scottish Gaelic given name is Torcadall, which is also Anglicised as Torquil.
Torquil was an Irish priest in the late Twelfth century: the first redorded Archdeacon of Dublin.
