Gruffydd Fychan ap Iorwerth

Sir Gruffydd Fychan ap Iorwerth Goch (c. 1150 – 1221) was a medieval Welsh Knight and Marcher Lord.

His father was a minor Welsh prince named Iorwerth Goch ap Maredudd, Lord of Mochnant, of the Royal House of Mathrafal.

His uncle was the last Prince of Powys, Madog ap Maredudd.

His great-grandfather was King Bleddyn ap Cynfyn, founder of Mathrafal, and King of both Powys and Gwynedd.

He was known by the epithet "y Marchog Gwyllt o Gae Hywel" ('the Wild Knight of Cae Howell'), Cae Howell being a manor near Kinnerley, Shropshire.

He was one of the earliest Knights of the Order of Saint John of Jerusalem, rivals of the Knight Templars, and also held the title of Knight of Rhodes.

This was during the reign of Frederick Barbarossa, the Holy Roman Emperor. Barbarossa visited Jerusalem in 1148 and was involved in the invasion of Damascus.

The Knights Hospitaller would later be under Emperor Barbarossa's protection in 1185. Gruffydd succeeded to his father's estates in Kinnerley, and resided at Cae Howel in the parish of Kunaston.
