    Other Events:

    • Alternate death: Aft 1235

    Notes:

    Many genealogical sources identify this Ebel de Grandison, who was husband of a daughter of Amadeus I of Geneva, as a son of another Ebel de Grandison (claimed to have died about 1173) and his wife Jordane, the older Ebel a son of Barthélemy de Grandison who died about 1158, and whose wife is said to be unknown.

    David Williams (citation details below) points out that model traces back to the research of the 19th-century Swiss historian Louis de Charrière, who postulated that Barthélemy's son Ebel could not have lived much beyond 1177 and that therefore the Ebel who appears in documents after that date must have been a son. This hypothesis was rejected in the mid-20th century by Swiss historian and genealogist Olivier Dessemontet, who argued that evidence for an additional Ebel was nonexistent, and further pointed out that Charrière had based his argument on his misunderstanding of a particular Latin text. Williams's piece, cited below, takes stock of the de Grandison pedigree in light of this and argues convincingly that Jordane was the wife of Barthélemy, not of Barthélemy's son Ebel, and that Barthélemy's son Ebel and supposed grandson Ebel were in fact a single individual who lived from about 1144 to the mid-1230s.
