I originally had Marguierite de Bourbon as wife of Guillaume; Turton states that Guillaume's wife is Beatrice (no last name); some on World Connect name her Beatrice de Beziers; still others name her Adelaide de Beziers; but I am following a fellow (I originally guessed Pablo was a Frenchman?, but Curt Hofemann says he is an Argentinian living in Miami) named Pablo Mera Gadea, who names her Adelaide Trencavel. She is probably the same person referred to as Adelaide de Beziers, as Adelaide's father was Raimond Trencavel, Viscount of Carcassonne, Rasès, Béziers, Agde, & Albi.

Note that, according to a posting to SGM by Nathaniel Taylor (citing tables by the Catalan genealogist Armand de Fluvia i Escorsa in two tables (s.v. AEnimes and AECarcasona) in the multi-volume 'Gran Enciclopedia Catalana', making no claims to accuracy), Adelaide Trencavel m. Sicard Viscount of Lautrec, and she had a sister Beatrice who m. Raimond VI Count of Toulouse.

Maybe it was her sister Beatrice Trencavel (per Turton (her 1st name) & World Connect people) that married Raimond, instead of Adelaide; or maybe Adelaide & Beatrice married the husbands that Nathaniel Taylor indicated. But, like I said, I am following Pablo Mera Gadea's pedigree. There are also numerous postings to SGM that name her Adelaide de Beziers, without giving her any ancestry.

The following excerpt from a post to SGM, 10 Jun 2003, by "History Writer", illustrates the confusion, but lends some support to my pedigree:

Chronologically, it would appear that Adelaide Trencavel, who apparently also is known (per the Theroff files) as Adelaide de Beziers (the Trencavels were also Vicomtes de Beziers), may have been a daughter of Raimond Trencavel I. Beatrix Trencavel is listed here as the wife of Raimond VI, Comte de Toulouse. However, Raimond Trencavel's daughter Adelaida Trencavel is listed as the wife of Sicard, Vicomte de Lautrec. In roglo, Sicard's only wife is listed as Agnes de Mauvoisin. If this is the Adelaide Trencavel who became the wife of Guillaume IV de Forcalquier, then she is a good candidate to be the matrilineal ancestress of Queen Victoria. This Adelaide's mother, Saura, is apparently of unknown origin.

I should note that in addition to Adelaide Trencavel (or Adelaide de Beziers) and Beatrix de Beziers, there is another woman listed as Garsende de Forcalquier's mother, she is Marguerite de Bourbon, according to Planche 546 in "Les Seize Quartiers Genealogiques des Capitiens" by J.-D. de Joannis (1987). Though it is unclear who Joannis's source is. Comments welcome. Best Regards.

Note: Todd Farmerie, in an adjunct to this post (referring to a post that was similar to the above post), thinks both "Beziers" and "Trencavel" are guesses, being not well documented.

Note: History Writer has Adelaide's mother as Raymond's 2nd wife Saura; Nathaniel Taylor's source also has Adelaide (although he doesn't connect her to Guillaume) by the 2nd wife. Following Pablo Mera Gadea's pedigree, I had Adelaide as daughter of Raymond's 1st wife, but am changing to agree with the sources.

Curt Hofemann, curt_hofemann AT yahoo.com, among numerous other references adds these to the pile of confused pedigrees:

Of the 270 listings on Rootsweb WorldConnect using Guillaume de Forcalquier & death date 1208 ± 10 years as search parameters, 95% of those listing his wife as Marguerite de Bourbon & a source, cite LDS Ancestor File AFN: PZ5V-PF, submitter: Medieval Families C/O Family History Dept (a dept. of the Family History Library itself)... Curt

Interestingly enough I have Adelaide de Bezieres as the wife of Guillaume IV and the mother of his daughter Gersende de Forcalquier. No other details. However in "Les Seize Quartiers Généalogiques des Capétiens" by J.-D. de Joannis planche 546 #43 , it shows Marguerite de Bourbon (no ancestry) as the wife of Guillaume and the mother of his daughter Gersende "fille unique". [Ref: Henry Soszynski 27 Dec 1999]

..See *Europaeische Stammtafeln*, ed. Schwennicke, Band III, Teilband 1 [1984], Tafel 118. The line ends up as follows:

1. Adelaide de Bezieres m. Guillaume IV C de Forcalquier (d. 1209)
..I've seen some speculation about the parentage and ancestry of Adelaide deBezieres, but I haven't seen it tightened up. [Ref: WAR 15 Aug 2000]

1. Gersende de FORCALQUIER b: ABT 1160 in Forcalquier, Alpes-de-Haute-Provence, Provence, France
