Stuart's "Royalty For Commoners" (82:28), Count of Dammartin, 1122, 1125-1129, High Chamberlain of France. Says he also married Clemence de Dammartin, liv. 1154. Per Evans, in "Genealogy Magazine" (15:53-63, 21:94): Aubri I, Count of Dammartin, maternal grandson of COUNT HUGH, also held in England at Norton and other places. He is said to have been born in 1110, but this seems too late, since his father would appear to have died by 1112, and there were younger sons. In addition, Aubri appears as a member of the French royal household 1122-9, suggesting a birth at least 20 years earlier. He is traditionally said to have married Amice de
Gloucester. He would seem to have been Count in 1166, and is said to have died ca. 1182. His son and heir was: AUBRI II, COUNT OF DAMMARTIN, who died 1200.

There is another item which appears to further support an earlier date for Aubri I's birth, as suggested above. According to the account of the seigneurs de Mello which appears in "Les Seigneurs de Nesle en Picardie" by Newman, one of Aubri I's younger half-brothers was Thibaut (son of Lancelin II de Beauvais by Aubri's mother), who was archdeacon of Beauvais from 1123 to 1166/7. This would appear to place Thibaut's birth soon after 1100, at the latest, and Aubri, as an older half sibling, had to have been born even earlier.
