I found more on De Clare. There was a Gilbert “The Red” (red haired) de Clare & son of Richard – one of the Earls of Gloucstershire (7th , I think) and he owned a whole bunch of other lands in 20 counties in England and Ireland. Joined the Montfort rebellion against the king. Married a jaon (Johanna) daughter of Edward II Longshanks. She was born in Acre – the site in the holy land where the Crusaders / Templar’s lost it all . He was born in 1243.
