Richard Sydgrave

Richard Sydgrave or Segrave (died 1425) was an Irish judge who held office as Chief Baron of the Irish Exchequer and served as deputy to the Lord Chancellor of Ireland; his family became among the foremost landowners in County Meath.
An earlier member of the Seagrave family, Stephen, had been Archbishop of Armagh 1323–1333; The exact relationship between the two men is unclear, although Richard was custodian of the See of Armagh in 1404.
His first recorded office was Clerk of the Hanaper in the late 1390s. He became a Baron of the Court of Exchequer (Ireland) in 1402 and Chief Baron in 1423; he also acted as Deputy Lord Chancellor. He appears to have died in 1425. In his last years, through the marriage of his eldest son Patrick (living 1445) to the heiress Mary Wafer, the family acquired the lands of Killegland, now Ashbourne, County Meath, where they remained until the 1640s;he also held lands at Newry and in County Galway, although it seems that he was never able to gain effective control of the Newry lands.
The Segrave connection with the Court of Exchequer continued, with two subsequent members of the family serving among its members.
