Odo the Good Marquis
Odo (or Eudes) the Good Marquis (fl. 11th century) was an Italo-Norman nobleman who ruled an unknown region of southern Italy. He married Emma, a daughter of Robert Guiscard, and they had at least three sons, Tancred and William, both famous crusaders, and Robert, as well as a daughter (name unknown) who married Richard of Salerno. Odo is known only in connection to his wife and sons.
There are many sources that identify Tancred's father as a margrave (marchio or marchisus, whence marquis)—which is enough to confirm that he was an Italian—but do not name him. Many further identify a brother named William who was also a "marquis's son". According to William of Tyre, "Tancred [was] the son of William the Marquis" (Tancredum Wilhelmi marchisi filium), but the Latin word filium (son) is probably an error by later copyists where originally it read fratrem (brother). That Tancred possessed a brother named William is affirmed by the Gesta Dei per Francos, which records a "William, son of the marquis, brother of Tancred" (Wilhelmus, marchisi filius, frater Tancredi) among the followers of their uncle, Bohemond of Taranto, on the First Crusade. In that same document Tancred is referred to only as "the marquis's son" (marchisi filius). Robert the Monk, listing the crusaders who accompanied Bohemond, mentions "the most noble princes, namely Tancred, his [i.e., Bohemond's] nephew and the marquis's son. . ." (nobilissimi principes, Tancredus videlicet nepos suus and marchisi filius), confirming his father's rank but not his name. The archbishop Baldric of Dol records, with more proper Latin, that Tancred was Robert Guiscard's grandson and the son of a marquis (marchionis filius). He also calls Tancred's brother William a marquis (marchisus). Guibert of Nogent, expressing some doubt that he has all his information correct, says that Tancred was the son of a certain marquis, accompanied his uncle Bohemond on the First Crusade, and that his brother William accompanied Hugh the Great (Tancredum marchionis cuiusdam ex Boemundi, nisi fallor, sorore filium; cuius frater cum Hugone magno praecesserat, cui Guillelmus erat vocabulum).
There are other sources pertinent to the identity of Tancred's father, since they mention his relation to Bohemond through the latter's sister Emma. Albert of Aix, a contemporary, confirms that Tancred was a son of Bohemond's sister (Tankradus sororis filius Boemundi), but does not mention either his father or brother. He does, however, mention that Roger of Salerno was a "son of Tancred's sister" (Rotgerum ... filium sororis Tankradi), who must therefore have been the wife of Richard of Salerno. Marino Sanuto the Elder records that Tancred was Bohemond's "nephew by his sister" (ex sorore nepos).
Two sources contradict the former, making Tancred a cousin and not a nephew of Bohemond, but do not name his father. The Gesta Francorum expugnantium Jerusalem of Fulcher of Chartres calls him "Bohemond's cousin" (Boiamundi cognatum) and Jacques de Vitry refers to "Bohemond with his cousin Tancred" (Boamundus cum Tancredo cognato ipsius).
Tancred's earliest biography, Ralph of Caen's Gesta Tancredi (Deeds of Tancred), praises him as "the most famous son of a famous lineage, [having] choice parents the margrave and Emma" (clarae stirpis germen clarissimum, parentes eximios marchisum habuit et Emmam). Tancred was "the son indeed of a father not in the least ignoble" (a patre quidem haud ignobilis filius), even though this father remains unnamed by Ralph and most other authors. Throughout the Gesta Ralph calls Tancred Marchisides, using the Greek suffix -ides, meaning "son of", thus "son of the marquis". Elsewhere he lumps together Tancred and Bohemond as Wiscardides ("sons/descendants of Guiscard"), even though he believes Emma to have been a sister and not a daughter of Robert Guiscard. He also add as a brother named Robert, "the Guiscardids, Tancred and his brother William and Robert" (Wiscardidas, Tancredum et fratres Willelmum Robertumque).
The only source to give Tancred's father the name Odo is Orderic Vitalis, who, like Ralph of Caen, believes him to be a brother-in-law and not son-in-law of Guiscard. In one passage, he writes that, seeing his end coming, "the magnanimous Robert [Guiscard], duke, count, etc., called around him Odo the Good, the marquis, his sister's [husband], and other relatives and nobles". When Orderic later lists the crusaders of 1096, he mentions "Tancred, son of the marquis Odo the Good" (Tancredum, Odonis Boni marchisi filium). Orderic's known erudition, and his contemporaneity with Tancred, make his testimony the best available on the latter's paternity. Only on the issue of Odo's wife, Emma, does Orderic seem mistaken. Since Tancred and his brother William were both young at the time of the First Crusade, it is unlikely that their mother could have been a daughter of Tancred's namesake, Tancred of Hauteville.

- Elsewhere Bohemond receives the epithet Wiscardigena, "born of Guiscard".
- Saulcy, 309–10, who argues that the use of Wiscardides throughout the text suggests that the initial assertion as to Emma's parentage is an error and that she was, as the other chroniclers say, a daughter of Guiscard.
