Many of the approximate years of birth have been adjusted to agree with those shown in website: which seem to make a better fit.]
Rollo Rollosson appears in only one other website:

[HEID251] Hrollager/Hrollaug Ragnvaldsson (born c.874, son of [GLUM279] Earl Rognvald, see GLUMRA), campaigned in Iceland. He married [FLAN282] Ermina le goz d'Avranches (born c.880, probably daughter of Count Baldwin I of Flanders & Judith Carolingian, see FLANDERS COUNTY). He died c.920, and Emina died c.935. [Ermina's parentage had been proposed by Alexandre Mazas in his "Histoire des Comtes de Flandres" (1843), which provides Hrollanger's issue with distinguished French royal ancestry.]

[HEID269] Horolf/Rollo Turstain/Thurstan of Heidmark (born c.909), baptised Robert, married [BLOI302] Gerlotte Blois (born c.910, daughter of Thibaut de Blois, see CHAMPAGNE COUNTY) Gerlotte died c.950, and Rollo died c.962.

[MONB291] Anslech/Anslac Turstain of Bastembourg (born at Tillieres, c.927, son of [HEID261] Horolf/Rollo) is described below under MONTFORT-SUR-RISLE.

[PERO301] Rollo Rollosson (born c.945, son of [HEID269] Horolf/Rollo) is described below under PERCY-EN-AUGE below.

[HEID271] Ansfrid I the Dane Rollosson (born c.935, eldest son of [HEID261] Horolf/Rollo), 1st Count of Hiermer, married (c.962) Helloe de Beulac (born c.937, daughter of Count Godfrey de Beulac, born 905). He died c.978, and Helloe died c.1000.

[HEID281] Ansfrid II Unfroi le goz (born c.963), Vicomte de Hiesmes, Steward of Normandy, married [NORM317] Guimara (believed to be a Breton lady, whose father was [NORM299] DUKE RICHARD I, see NORMANDY DUKEDOM). Ansfrid died 1034.

"Domesday Descendants" (K.S.B. Keats-Rowan, 2002) mentions that a charter of the abbey of Montivilliers features the nun Wimardis, widow of Ansfrid the steward who gave Ectot [possibly Saint-Germain-d'Ectot, in Calvados] to this religious house, as later attested by Robert. The book also mentions that Robert de Moyaux [in Calvados] (at the request of his mother Wimardis) gave to this religious house land that Ansfrid had held in the forest of Rouvray.

A community of nuns was established (1035) at Montivilliers by DUKE ROBERT OF NORMANDY, with the first abbess being Beatrice (widow of Ebles de Turenne, illegitimate daughter of DUKE RICHARD I OF NORMANDY). This strongly suggests that Guimara and Abbess Beatrice were half-sisters, with the same relationship between Guimara and Emma of Normandy (who married in April 1002 [WESK349] King Aethelred II the unready), thus making Ansfrid's wife as the sister-in-law of the Anglo-Saxon king. Guimara's name is absent from a list of Duke Richard's children, but this could be because she was not born in Normandy, as her mother was a Breton.

[AVRX291] Thurstan le goz (born c.995, son of [HEID281] Ansfrid II), Seigneur de Hiesmes, is described under AVRANCHES).

[ESSE341] Robert "FitzWimarc" (born at Moyaux, Calvados, c.1007, son of [HEID281] Ansfrid II & "the noble lady Guimara"), is described under RAYLEIGH FEUDAL LORDSHIP.

[HEID292] Louis le goz, Vicomte d'Avranches (son of [HEID281] Ansfrid II), married Adelisa of Brittany.

[HEID302] Louise (daughter of Louis) married [LAME391] Guillaume de la Mare, see DE LA MARE NORMANDY).



[MONB291] Anslech/Anslac Lancelot Turstain of Bastembourg a.k.a. Oslac de Briquebec (born at Tillieres, son of [HEID261] Horolf/Rollo, see HEIDMARK above), Lord of Briquebec and Montfort-sur-Risle, married Gillette de Beaumont (possibly daughter of Bernard the Dane, see HARCOURT-1). Anslech died c.974.

[MONB302] Eremburge (daughter of Anslech Turstain) married [BERD311] Torf le riche, see HARCOURT-1.

[MONB303] Catherine de Briquebec (daughter of Anslech) married [ARGO291] Bernard d'Argouges (see ARGOUGES).

[MONB301] Thurstan de Bastembourg (son of Anslech Turstain), Seigneur de Bastembourg, Montfort-sur-Risle and Bricquebec, married Aubree. He died 1021.

[MONB313] Anceline de Montfort-sur-Risle (born c.965, "sister of Turstain", but shown elsewhere as daughter of Turstain) married [HARC301] Turquetil/Turqueville/Tanqueraye, de Neufmarche (born c.960, see HARCOURT-2).

[MONB312] Gisla de Bastembourg (born c.975, daughter of Thurstan) married [ECHA311] Seigneur Giroie (see ECHAUFFOUR).

[MONB311] Hughes I the bearded Thurstan de Montfort (born c.980, son of Thurstan), Seigneur of Pont-Author and Montfort-sur-Risle, killed in battle (1040) defending DUKE WILLIAM II OF NORMANDY (later the Conqueror). Other version says he and Walkelin de Ferrieres were each killed either in a jousting contest or a feud.

[MONB331] Hughes II (born c.1030) took part in the Battle of Monthermer (1054) and the Battle of Hastings (1066). He was Constable of Normandy then later of England, and afterwards Warden of Dover Castle. He received 114 manors in England, and became a monk at le Bec (c.1088). He married 1. [BEAF332] Alice (daughter of Richard Beaufour, see BEAUFOUR); then 2. ---.

[MONB342] Alice (daughter of Hughes II, by his 1st wife Alice), Dame de Montfort-sur-Risle, married [GANT341] Gilbert de Gant, see GANT.


[PERO301] Rollo Rollosson (born c.945, son of [HEID269] Horolf/Rollo, see HEIDMARK above).
