Kenneth I

First King of Scots

Cináed mac Ailpin (Modern Gaelic: Coinneach mac Ailpein), commonly anglicised as Kenneth MacAlpin and known in most modern regnal lists as Kenneth I (810 – 13 February 858), was a King of the Picts who, according to national myth, was the first King of Scots. He was thus later known by the posthumous nickname of An Ferbasach, "The Conqueror". The dynasty that ruled Scotland for much of the medieval period claimed descent from him, and the current British monarch, Queen Elizabeth II is descended from him through Malcolm III, Robert the Bruce and James VI and I.

Donald I

Kenneth I's brother

Domnall mac Ailpín (Modern Gaelic: Dòmhnall mac Ailpein,[1] anglicised sometimes as Donald MacAlpin, known in most modern regnal lists as Donald I); (812 – 13 April 862) was King of the Picts from 858 to 862. He followed his brother Kenneth I to the Pictish throne.

Constantine I

Kenneth I's son

Causantín or Constantín mac Cináeda (in Modern Gaelic: Còiseam mac Choinnich; died 877) was a King of the Picts. He is often known as Constantine I in reference to his place in modern lists of Kings of Scots, but contemporary sources described Causantín only as a Pictish King. A son of Cináed mac Ailpín ("Kenneth MacAlpin"), he succeeded his uncle Domnall mac Ailpín as Pictish King following the latter's death on 13 April 862.
