  Research Notes:

"Rivallonus…Rufus frater Goffredi de Dinan" donated property to "monachis in Valle juxta castrum [Dinan]", with the consent of "Ozio uxor Goffredi et filii eius…Oliverius, Alanus" by undated charter. Geslin de Bourgogne states that he was the second son of Geoffroy, held the fief of Bécherel, founded a priory at his castle (whose archives are now lost), and later inherited the castle of Léhon. The 1130 Pipe Roll records "Alano de Dina" in Dorsetshire, Cambridgeshire, and Huntingdonshire (twice). "Alanus de Dinanno" confirmed the donation to the abbey of Sainte-Marie-de-Boquen by "Hingaudus Judicaeli quondam filius" with the consent of "fratrum suorum Gauterii…et Rollandi", with the consent of "Oliverius filius Gaufredi de Dinanno qui tunc erat in mea custodia", by undated charter dated to the mid-12th century. "Alanus de Dinan" donated property to Lehon by charter dated 1149, witnessed by "Roberto fratre meo…". The 1156 Pipe Roll records "Alano de Dinan" in Berkshire, "in Gainz" yielding £15.

The Chronicon Britannico Alter records that "Alanus Dinanensis" was killed in 1157. The Chronicon Britannico records the death in 1157 of "Alanus Oliverii filius" and his burial "apud S. Jacutum".
