Hugh de Say, of Richard's Castle, 4th baron of Burford - Identity of his wife (or his mother) is suspect

Fixed. Eustachia de Say was not a Clifford. (Uncertain who her parents *were*, but not Cliffords.)

The Cliffords are a bit of a rats' nest in this area: Walter FitzRichard de Clifford, 1st Baron Clifford

Children all over the place, indicating either multiple marriages or barnacles.

By the way, the FitzHugh Says may have been "lords" of Burford, in the sense that they held the place and bossed the peasants around, but they weren't barons. MedLands has them under "Untitled".
