User ID: V403.
"FERGUS, usually styled 'de Galweia,' or 'of Galloway,' who appears as a witness to a charter by King David I.
Fergus married Elizabeth FITZROY, daughter of Henry I King of England and Unknown.1 (Elizabeth FITZROY was born about 1105.)
"He (Fergus) is said to have married Elizabeth, the youngest natural daughter of King Henry I. of England, but the authorities quoted by Chalmers, who makes the statement, do not bear out his assertion. On the other hand, Hoveden and Benedict Abbas, both refer to Uchtred, eldest son of Fergus, as a cousin or relative of King Henry I. This epithet is not applied to Gilbert, and he may have been a son by a second wife."
