Alberic II (died 1183) was the Count of Dammartin, possibly the son of Aubry de Mello, Count of Dammartin, and Adela, daughter of Hugh I, Count of Dammartin.
[1][2] What little is known for sure about Alberic II is confounded by the preponderance of noblemen of the same name in both France and England.
What is known is that he married Clémence of Bar, daughter of Reginald I "One-Eyed", Count of Bar, one of the leaders of the Second Crusade, and Gisèle de Vaudémont, daughter of Gerard I, Count of Vaudémont.
The discussion in Aubry, Count of Dammartin, provides some insight into how Alberic III came to claim the countship.
Further complicating the genealogy, Clémence, widowed, married Renaud II, Count of Clermont-en-Beauvaisis, her second husband and his second wife.
