  Research Notes:

The Chronicle of Abingdon records a precept addressed by William I King of England to "Lanfranco archiepiscopo, Roberto de Oilleio et Rogero de Pistri" in favour of the monastery of Abingdon. A charter dated to [1164/74] records that the burial at Lanthony of "domini Milonis comitis Herefordić" and records that "Rogerum de Pistres" was granted "custodi castri Gloucestrić" after the conquest and that his family succeeded him "Durandum de Pistres fratrem eius" and "filium…Walteri de Gloucestria".

Sheriff of Gloucester. He probably died shortly before 1086: his son is recorded with his father’s name holding property in Domesday Book, and his son made donations for his father’s soul by charter dated that year... ²
