Richard FitzGilbert De Clare, eldest son of Gilbert and Eva, was born before 1105. He first bore the title of Earl of Hertford. He invaded Wales with an army and became lord of vast possessions there by power of his sword, but requiring other matters of moment from the king, in which he was unsuccessful, he reared the standard of revolt, and soon after was slain in a skirmish with a few Welsh yeomen, near Abergavenny, on April 15, 1136.
In 1124 he removed the monks out of his castle at Clare into the church of St. Augustine, at Stoke, and bestowed upon them a little wood, called Stoke-Ho, with a doe every year out of his park at Hunedene.
Richard married Alice Meschines, daughter of Ranulph(Ralph?) de Meschines, 1st Earl of Chester, and sister of Ranulph, 2nd Earl of Chester.
Richard married Alice (Adeliza) de Meschines, daughter of Ranulph "de Briquessart" Lle Meschin Earl Of Chester and Lucy Countess of Chester, before 1116. (Alice (Adeliza) de Meschines was born about 1094 in Hertford, Hertfordshire, England and died in 1128.)
