GODFRIED van Aarschot, son of ARNOUT [IV] Graaf van Aarschot & his wife --- ([1130/40]-1174 or after). His birth date range is estimated from the marriage date of his son by his second marriage. He succeeded his father as Graaf van Aarschot. Godfried sold the county of Aarschot to the Duke of Brabant in 1172 to finance his participation in the Third Crusade[452].
m [firstly] [ADA de Louvain, daughter of GOSSUIN de Louvain & his wife ---. Herckenrode names "Ade fille de Gosuin de Louvain" as wife of "Godefroid d´Arschot" but cites no corresponding primary source[453]. The husband of Ada is presumably identifiable with Godfried, son of Arnout [IV], but Herckenrode´s genealogy is confused and does not reflect the primary sources which have been identified during the preparation of the present document. No other document has yet been found which names Godfried´s wife.]
[m secondly [ALIX [d´Albret] daughter of [ALBERT ---] & his wife [--- de Bretagne]. The information about this supposed second wife of Godfried is not contemporaneous. "Alix d´Albret" is named as second wife of Godfried by Liekens[454]. He quotes a manuscript genealogy which shows several families from the town of Louvain, written by Peeter Eckman and dated to the second half of the 18th century (Liekens says that Eckman was born in Louvain in 1742 and married Anna Maria Verhoven there in 1767). ; He quotes the manuscript as stating that "Godefroy grave van Arscot, sone Arnoldi" married "Alixa d´Albret, suster van Alin d´Albret" with the consent of "den grooten prins in bretanie", adding that Alain and Godfried participated in the Third Crusade and were captured together "in Damiolen". This reference is a puzzle. No "Alain" d´Albret is recorded in the second half of the 12th century, and the alleged involvement of Brittany in the affairs of the Gascon Albret family cannot be explained, unless the reference relates to Geoffrey Duke of Brittany whose father Henry II King of England was suzerain of Gascony de iure uxoris at that time. Peter Crombecq refers to another manuscript source (dating unspecified), also from Louvain, which states that the wife of "Godfried van Aarschot" was "Alix" daughter of "Albert", whose wife was "--- van Bretagne", the latter being sister of "Alix princes van Bretagne"[455]. It is not clear whether the manuscript source cited by Crombecq predates the Eckman genealogy, or whether it was based on the latter. The reference to "princes van Bretagne" is clearly anachronistic and does not inspire confidence. However, this second source suggests the possibility that "d´Albret" in the first source may simply be a corruption of the name "Albert" and that there is no link with the Gascon d´Albret family at all. The report in Herckenrode concerning this supposed person is even more confused. He refers to "Alix de Bretagne, sœur d´Alin d´Albret" as wife of "Godefroid d´Arschot", citing no corresponding primary source[456]. However, it is clear from his text that he is referring to Godfried, husband of Emmissa de Valenciennes (see above), not to Godfried son of Arnout [IV]. No primary source has yet been found which suggests that Godfried married a second time, let alone indicates the identity of his supposed second wife. Until such source emerges, it is more prudent to show this supposed second marriage is square brackets and express extreme caution about the identity of "Alix d´Albret".]
