The Knight of Glin (Irish: Ridire an Ghleanna;[1] dormant 14 September 2011), also known as the Black Knight or Knight of the Valley,[2][3][4] was an hereditarytitle held by the FitzGerald and FitzMaurice families of County Limerick, Ireland, since the early 14th century. The family was a branch of the FitzMaurice/FitzGerald Dynasty commonly known as the Geraldines and related to the now extinct Earls of Desmond who were granted extensive lands in County Limerick by the Crown. The title was named after the village of Glin, near the Knight's lands. The Knight of Glin was properly addressed as "Knight" (not, as one might expect, "Sir ______ FitzGerald").[4]
The family name "FitzGerald" comes from the (Norman) French "Fils de Gerald," i.e. "Son of Gerald."
The coat-of-arms of the Glin family is: Ermine: a saltiregules. Crest: a boar passant gules, bristled and armed. Motto: Sahnit a Boo. The arms of the various families in Ireland are similar. The Knights of Glin bear as supporters two griffins collared and chained, and have a second crest: a castle with two towers, issuant from the sinister tower a knight in armor holding in the dexter hand a key proper. The Glin family seat is at Glin, Glin Castle, County Limerick, Ireland.[5]
