"ROLAND le Strange . m MATILDA, daughter of [RALPH FitzHerluin alias RALPH de Hunstanston & his wife Heloise de Plaiz]. ... Roland & his wife had four children: ...
a) JOHN [I] le Strange (-before 29 Sep 1178). His parentage is confirmed by the charter dated to [1157/60] in which "Johannes Extraneus" donated land to Castle Acre priory, for the souls of "patris mei Rollandi et Matildæ matris meæ et Hamonis fratris mei". "Radulfus Lestrange" granted land in Wormgay, Norfolk to St Katherine´s, Blackburgh by charter dated to , witnessed by "..:Widone Lestrange…Iohe Lestrange". "Johannes Extraneus et Wido frater eius, Johannes filius Johannis Extranei, Wido et Hamo filii Widonis Extranei, Thomas filius Roberti filii Noelli…" witnessed the undated charter under which "Willielmus filius Willielmi filii Alani" donated "villam…Parva Buldewas" to Buildwas Abbey, Shropshire. The 1157 Pipe Roll records "Johi Extaneo" in Shropshire with revenue Military fee certifications in the Red Book of the Exchequer, in 1166, record that "Johannes Lestrange" took one knight´s fee "Cheswrtha" [Cheswardine] from "Roberti di Staffordia" in Staffordshire.
m HAWISE, daughter of ---. Her marriage is confirmed by one copy of a charter dated to [1177/80] in which "Johannes Extraneus" confirmed a donation of land in Webblescowe to Haughmond abbey, for the soul of "Hawise his wife", witnessed by "Wido my brother, Ralph his son, Hugh le Strange, Marescote, and Henry his son". John & his wife had two children:
i) JOHN [II] le Strange (-before 20 Jan 1234). ...
ii) WILLIAM le Strange
iii) HAMO le Strange (-before 1203)."
"... Here, then, we have proof that Roland was an ancestor of the four successive John le Stranges, the first of whom appears in public life as early as 1155, so that, as Eyton points out, Roland must have lived at least as early as the reign of Henry I. Another deed, discovered by Eyton in the Castleacre Chartulary, settles decisively that Roland le Strange was the father of John le Strange (I) and his three brothers, and also gives the name of Roland's wife as Matilda. This charter must have passed between 1160, when Hamo died, and 1179, when John died. ...
