I have stated above that Baldwin II was elected to succeed as king of Jerusalem because he descended matrilineally from St.Ide the mother of Godfrey and Baldwin de Bouillon;however, I may have to revise that opinion. Although I have read it stated in many sources and still cannot rule it out, nevertheless I have found evidence that he was chosen rather for another cause: St. Ida elsewhere called the daughter and sometimes the granddaughter of Lohengrin the Swan Knight and Clarissa duchess of Bouillon, may have been the sister of Godfrey III d.1076 and the daughter of Godfrey II. This implies a Godfrey I and the chart I am consulting makes no mention of Lohengrin;yet, this is a very popular and persistent legend so I would not lightly dismiss it. Actually this version of things seems odd as it has St. Ida married to Eustache II of Boulogne and yet naming her ELDEST son Eustache III C of Boulogne--which, makes sense actually, following her husband's ennumeration--but her second son Godfrey IV d.1100. This, of course, is the famous Godfrey of Bouillon;but, why would he follow a naming tradition and an ennumeration from his mother's line? Unless he was his maternal uncle's heir? Her third son, of course, was Baldwin I King of Jerusalem 1100-1118. But, this same chart at least demonstrates no descent rom St. Ida at all for Baldwin II! Odd because, this is often cited to have been the case, even the reason for his election. This source, in fact says that the Bouillon name came not from St.Ida but from her husband's family, Bouillon having been but a variation of Boulogne. Eustache I of Boulogne (Bouillon) m. Mahaut de Louvain and had 2 children: Eustache II of Boulogne who m. St.Ida and Judith d.1081 who m. Manasses II C of Rethel;their son, Hugh I C of Rethel d.c.1118 m. Melisende sis. of Isabella who m. Lord Joscelin Courtenay. Hugh and Melisende are here credited with having been the parents of Baldwin II King of Jerusalem 1118-1131;however, I can state that in many other sources he is named Eustache (le?) Bourg and described as a descendant of St.Ida. Well, perhaps she was also his great-grandmother through some other line of descent. Family connexions having been as close as they were, it does not do lightly to rule out the possibility. Besides, Rodney Dennys who, I think has served as a herald or King of Arms in the College of Arms of England, has described Baldwin II as this Eustache and a great-grandson of St. Ida and, surely such an expert would know!
