There is much discussion and disagreement about this line. Dammartin ancestry very uncertain, and uncertain whether Alberic is I or II. The best discussion, with evidences, in Gen. Mag. XV 53-63, XXI 94.^[3]
Turton shows Clemence as marrying both Renaud II of Clermont and Alberic II of Dammartin.
However, Weis shows her as marrying Lancelin I of Dammartin (no issue), Renaud II of Clermont, and Thubaut III of Nanteuil-le-Handouin, so the marriage to Alberic is probably incorrect.
