It seems irrational that this profile shows two given names.
If there's a rationale for a two-named "de Pitres", is it plausible and source-able?
FMG shows that Dreux or Drogo had a daughter named "Emmeline" and a daughter whose name is unknown.
Cawley and crew do not include a "Berthe" as daughter.: http://fmg.ac/Projects/MedLands/WALES.htm#_Toc389126145 .
