2. [EMMA ([1045/55]-). She is named Emma in the Gesta Tancredi and by Tudebodus Imitatus, both of whom state that she was the sister of Robert "Guiscard"[312]. Orderic Vitalis also says that she was the sister of Robert "Guiscard" but does not name her[313]. William of Tyre records "Tancredus" as "ex sorore nepos" of Robert Guiscard[314]. Albert of Aix names her son "Tancredus filius sororis Boemundi"[315]. Guibert, on the other hand, refers to "Tancredum, Marchionis cujusdam ex Boemundi, nisi fallor, sorore filium, cujus frater cum Hugone Magno præcesserat cui Guillelmus erat vocabulum, et quemdam qui dicebatur de priima civitate Richardum nominatiores agnovimus, virum sane pulchra corporis habitudine spectandum: quem pro Constantia, Boemundi conjuge, ad Franciæ regem vidimus legatione perfunctum"[316]. Tancred is described as Bohémond's nephew "so nevolo de una sorella" in Itinerario di la Gran Militia a la Pavese[317]. Chronologically it is more probable that Emma was the daughter, rather than sister, of Robert "Guiscard". If she had been his sister, she could not have been born much later than 1030, which appears inconsistent with the likely birth dates of her two sons in the early 1070s. If she was his daughter, it is unlikely that she could have been born from Robert's second marriage as she would have been too young to have given birth in the late 1060s/early 1070s. It is also possible that Emma was Robert's illegitimate daughter, although this seems improbable if her husband was as illustrious as appears from his title, and also inconsistent with her son marrying the daughter of the king of France.

m ODO [Guglielmo] "le Bon", son of --- (-after 1085). Marchese. Orderic Vitalis records that Tancred was the son of "Odonis boni marchisi"[318]. William of Tyre, on the other hand, records Tancred as "Tancredus Willelmi marchionis filius"[319]. "Tancrede figliolo di Vuillermo Marchion" is also recorded in Itinerario di la Gran Militia a la Pavese[320]. He is simply called "Marchisum" in the Gesta Tancredi, which states that Tancred was "a patre quidem haud ignobilis filius"[321]. Tudebodus Imitatus refers to the father of Tancred as "qui Marchusus dictus est"[322]. His sons are consistently referred to as "Marchisi filius" in contemporary chronicles concerning the First Crusade. These references suggest that he was alive at the time and, because he is referred to without a name, that he was such a well-known figure as to be recognisable only by his title. The illustrious marriage of Tancred son of "the Marquis" to the daughter of Philippe I King of France in 1106 is also best explained if the bridegroom had good family connections on his father's as well as his mother's side of the family. The names "Guglielmo" and "Odo" suggest a family relationship with the northern Italian family of the Marchesi di Monferrato, although it is not known what connections they may have had with southern Italy. Pushing this speculation further, the name of the first wife of Guglielmo [III] Marchese di Ravenna, the father of Ranieri Marchese di Monferrato, is unknown. Assuming that his connection with southern Italy could be proved, it is not impossible that Guglielmo married firstly Emma daughter of Robert "Guiscard" and was father by her of Tancred. The highly speculative nature of these conjectures must be emphasised. However, no other contemporary marchese Guglielmo or Odo has so far been identified in records relating to either northern or southern Italy. Orderic Vitalis records that Robert "Guiscard" Duke of Apulia summoned "Odon the Marquis", among others, to his deathbed in 1085[323], which also gives some indication of the relative importance of Odo/Guglielmo in contemporary southern Italy.]

• Emma d'Altavilla, sorella di Boemondo I d'Altavilla.
• Emma era anche il nome di una sorella di Roberto il Guiscardo, la cui omonimia ha spesso creato confusione in alcuni autori, i quali, confondendo il grado di parentela tra i due rampolli della casa normanna, hanno erroneamente indicato Tancredi quale cugino di Boemondo principe di Antiochia, anziché suo nipote[1].

• wiki treccani contrastanti Figlia di Tancredi d'Altavilla, come sembra accertato, e sorella di Roberto il Guiscardo e di Ruggero, raggiunse i fratelli in Italia, quando questi avevano ormai consolidato la loro potenza, intorno al 1080.

Secondo alcuni cronisti, l'A. sarebbe stata invece una delle figlie del Guiscardo, ma ciò è contraddetto dalle fonti coeve (fra cui particolarmente probante Raoul di Caen, De rebus gestis Tancredi principis, cap. 1,confidente e poeta del figlio dell'A., Tancredi, principe di Antiochia), che la dicono sorella e non figlia del Guiscardo.

Intorno all'anno 1089, quando insieme con le nozze di Ruggero, conte di Sicilia, con Adelaide del Vasto, si contrassero numerosi parentadi fra Normanni e nobili subalpini, l'A. sposò Oddone "Marchisius" o "Bonus Marchisius", a cui diede almeno due figli, Tancredi, il famoso crociato, e Guglielmo, morto in Terrasanta. Essa era morta parecchi anni prima del 1126, quando una Sichelgaita, vedova di Oddone "Marchisius", fece una donazione, per sé, per i figli e per la buona memoria del marito
