Robert de Neubourg
He was the fourth son of Henry de Beaumont, 1st Earl of Warwick, and inherited his father's Normandy lands, holding Neubourg from Waleran de Beaumont, 1st Earl of Worcester, a Beaumont family cousin, as Comte de Meulan. He was Sire du Ponteaudemer, and acquired other lands at Winfrith, Dorset. He took part in the Norman rebellion of 1118–1119, against Henry I of England, around William Clito. The immediate issue was a conflict with his feudal overlord, Waleran. He rebelled for a short time only, being burnt out of Neubourg. It was only in the early 1140s that Robert and Waleran resolved their difficulties formally.
He married Godehildis de Toni (or Conches). His eldest son Henry de Neubourg (c. 1130 - 1214) inherited his lands in Normandy, while his younger son Roger de Newburgh (c. 1135 - 1192) inherited his lands in Dorset. Roger was responsible for the relocation of Bindon Abbey to Wool. Henry's lands were inherited by his son, Robert II de Neubourg (c. 1175 – c. 1260).

- There does not appear to be any direct evidence relating Roger de Newburgh to Robert de Neubourg, but a reference in Kirby's Quest (1284) makes it plausible. This reference (see ) shows that part of Hasler Hundred in Dorset had been owned by the Newburgh family "since time immemorial". And Domesday Book shows that Robert's grandfather, Roger de Beaumont had owned three manors in Hasler Hundred, Creech, Steeple and Church Knowle. This is quite strong circumstantial evidence of a relationship.
