[SUANEHILDIS (-31 Mar [1100]). The Annalista Saxo names "Bertrada, soror Suanehildis comitisse de castro quod dicitur Lon in Hasbania, cuius filius fuit Arnoldus comes Mogotiensis prefectus" as wife of Graf Dietrich (identified as Dietrich I Graf von Katlenburg)[360]. As noted above, no primary source has been identified which indicates that Bertrada was the daughter of Dirk III Count of Holland. Nevertheless, from a chronological point of view Count Dirk is the most likely father, assuming that Bertrada was a member of this family. "Arnoldus comes Mogotiensis prefectus" in this passage must be identified as Arnaud [I] Comte de Looz, who is recorded as the son of Emmo Comte de Looz. If that is correct, Suanehildis was the wife of Emmo. From a chronological point of view, the suggestion is feasible: the birth of the children of Count Dirk III must be dated to [1010/35], while Comte Emmo´s children were probably born in [1040/60]. The necrology of Liège Saint-Jacques points to this being the correct solution when it records the death 31 Mar of "Spannehildis comitissima de Los" and her donation[361]. Verdonk indicates that she died in 1100 on a pilgrimage to Rome[362]. [The Vita Andreæ, first abbot of Averboden, in the Chronicle written by Nicolas Hogeland Abbot of Middelburg, records that "comitis Arnoldi Lossensis" descended "ex parte matris" from "Cliviæ comitibus"[363], which would be inconsistent with this hypothesis but, as pointed out below, Klaversma notes that this source is a 17th century forgery and is therefore unreliable[364].] m EMMO Comte de Looz [Immo], son of [GISELBERT Comte de Looz] & his wife [Liutgarde de Namur] (-17 Jan 1078]).]
