Born in Saye, Normandy, Picot rose from obscurity to become Sheriff of Cambridgeshire as early as 1071 until at least 1090.
[1] He treated Cambridge (then known as Cantebrigge or Grentebrige) as his own, knocking down 27 houses to build Cambridge Castle (probably initially of wood), confiscating land, building mills, seizing goods and raising taxes.
The Abbot of Ely described him as "A hungry lion, a ravening wolf, a cunning fox, a dirty pig and an impudent dog".
[3] Picot's son and heir Robert became implicated in a conspiracy against King Henry I, and fled the country.
His estates were forfeit and given to Pain (or Paganus) Peveril who had been the standard bearer to Robert Curthose in the Holy Land.
