Note 27 — Chapter I · THE BOY DUKE 1157-1179
Reading edition
“Robertus de Silli,” Mat. for Hist. Becket, vi. 456; “Robertus de Selit,” Geoff. Vigeois, 318; “Robertus et frater ejus de Silleio,” R. Torigni, a. 1167. The name appears as “de Silliaco” in Mat. for Hist. Becket, vii. 165, 178, 247, 606, 610, 616. It cannot be Sillé in Maine as I suggested in Angevin Kings, ii. 137; it can hardly be anything else than Seilhac.
