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).
