Archambaud II "Talairan", comte de Périgord - Discrepancies & questions around de Périgord

According to Medlands:
1. Hélie VII "Talairan", comte de Périgord and Marguerite de Limoges only had one child, Archambaud de Périgord. I will be detaching the other children currently attached unless some reliable sources are cited in which case they can be added back in. These children are:
Boson de Talleyrand, seigneur de Grignols ,
Almodis de Talleyrand ,
*
2. The name of Archambaud’s wife is not known and yet we have him linked to Marie Bernard d'Anduze.... I will leave this relationship for now but this is a record that it is yet to be confirmed.
