Biography

Name

  • Geoffrey, Duke of Brittany [1]
  • Geoffroi I, Duke of Brittany [2]
  • Geoffroy de Bretagne [3]

Parents

He was the son of Conan I "le Tort" Duke of Brittany & his wife Ermengarde d'Anjou ([980]-20 Nov 1008). His parentage is confirmed by the Chronico Sancti Michaelis which records that "Gaufridus Dux Britanniæ filius Conani filii Juhelli Berengarii" died in 1008 "dum pergeret Romam causa orationis". [3]

992 Succession

He succeeded his father in 992 as Geoffrey I, Duke of Brittany. A charter dated 1026 recalls that "Gaufridus, Conani Curvi filius" was killed "apud Concuruz prelium". The Chronicon Kemperlegiense records the death "dum pergeret Romam" in 1008 of "Gauffridus Dux Britanniæ filius Conani filii Iuhaëlis Berengarii". [3]

Geoffrey, Duke of Brittany, succeeded his father as Count of Rennes in 992 & held Brittany as a duchy under the sceptre of Normandy. Slain while returning from a pilgrimage to Palestine in 1008. Married in 996 to Hewise, daughter of Richard I, Duke of Normandy.[1]

When Geoffrey succeeded to Brittany he had several problems: Blois was encroaching on his territory, Vikings were threatening his shores, and he had to decide whether to accept the protection offered by Anjou. He chose to align himself with the Duke of Normandy, marrying Hawise of Normandy, daughter of Richard I of Normandy in 996 [1]

Geoffrey, Count of Rennes, assumed the title Duke of Brittany in 992 but the title was never recognized by the French king at the time and was not formerly legitimized until 1213. By the time of Count Geoffrey's reign, his claim to suzerainty over all of Brittany was weak and he had virtually no control over western Brittany and Nantes. [1]

996 Marriage

He married between 996 and 999 Hawise of Normandy, legitimated daughter of Robert I, Duke of Normandy, by his second wife Gonnor. [2]

He married in 996 Havise de Normandie, daughter of Richard I I "Sans-Peur" Comte [de Normandie] & his second wife Gunnora --- (-21 Feb 1034).Guillaume of Jumièges names “Emma...secunda Hadvis...tertia Mathildis” as the three daughters of Richard and his wife “Gunnor ex nobilissima Danorum prosapia ortam”, adding that Havise married “Goiffredo Britannorum comiti” by whom she had “Alanum et Eudonem duces”. [3]

1008 Death

Geoffroi I, Duke of Brittany, died 20 Nov 1008. His widow, Hawise, died 21 Feb 1034. [2]

A charter dated 1008 records that, after the death of "Gaufrido comite Britanniæ", "filii eius Alanus et Eudo cum matre eorum Hadeguisia" restored the abbey of Saint-Méen. "…Aduise matre eorum comitum…" signed the charter dated to [1013/22] under which "Alanus et Egio Britannorum monarchi" founded the priory of Livré "in pago Redonensi"[136]. The Chronico Kemperlegiensi records the death "1034 IX Kal Mar" of "Haduisa comitissa Britanniæ, vidua Gauffridi"[137]. [3]

"Son" Geoffroi may be a clumsy duplicate of his own "father", and "Kadwige" a duplicate of Hawise.
Unfortunately, too many people don't read the bios, which means that the data field and connections really have to be as conservative as possible to keep people from imagining connections that just aren't there.

But moving slowly is always good. My first step is always to document what we know about the children in a section about issue; that tends to bring clarity to who needs to be disconnected and who needs to be retained!

There is not one sourced profile in "Emme Lupus"'s line until several generations after it reaches a Cotton family in England. This does not look credible enough to be retained.

My preference would be to disconnect the purported children and document in all bios. Perhaps post a G2G?

My solution would be to post a warning in the bio that the parentage cannot be confirmed and leave the profile alone until more information is available. We know that dates are often guesses, and cannot be thought of as reliable in these old texts. I see FMG pages referenced.
posted by Sheri (Petersen) Sturm
Evenus, Emma, Geoffroy, Emme Lupus and Robert D'Ivry are all currently linked as children of Geoffroi, Duke of Brittany, but confirmed as children neither by Richardson nor FMG. Are there any other sources which can confirm these children, or should they be de-linked?
posted by Jack Day
Geoffrey died in 1008 yet fathered a son, Robert, in 1020. This is not possible.
