My children have among their ancestors the couple Wouter 2 van DENDERMONDE, lord of Dendermonde, and Adelisa/Adela van BUYSSCHEURE. This Adelisa would have had as a second husband Gerard 3 van GRIMBERGEN.
Although she married two powerful lords, her own identity is unclear, Warlop doesn't give her parents while many people pretend she was daughter of Renaud de ROZOY/ROSOY and Julienne de RUMIGNY without giving any reference.
This alleged parentage comes from Christophre Butkens in *Trophées tant
sacrés que prophanes de la duché de Brabant* (1637), based on his
arbitrary identification of Adelisa's documented brother Roger of Marck
as Roger of Rosoy. André Du Chesne in *Histoire généalogique de la
maison de Béthune* (1639) called her Adelise de Locres, asserting
without proof that she was heiress of this family.
Warlop qualified Roger as Adelisa's "brother (in-law)", but this
alternative too is unproven. He witnessed several of her charters as her
brother ("frater meus") and the same relationship was stated plainly in
a charter of Philippe I of Namur dated 12 March 1209 (in the extant
original, miscopied as 1204 in the cartulary of Revensberghe abbey:
"nobilis mulier Aelidis de Tenremunde pro remedio anime sue et
predecessorum suorum annuente filio eius Willelmo ... dedit per manum
meam totam decimam quam habebat in parochia de Albeke que fuit domini
Rogeri de March. fratris sui et tenebat in feodo de comite Flandrie in
perpetuum elemosinam ecclesie Sancte Marie de Outhoua", see folio 3r-v
This suggests that Roger was a Flemish knight rather than a French
seigneur - in any case, there is not enough evidence to pin down his
identity or Adelisa's family.
