Question: Margaret of Huntingdon (died before 1228) was the eldest daughter of David, Earl of Huntingdon (died 1219) and his wife, Maud (died 1233), sister of which earl that died in 1232, was one of the "old school" of Anglo-Norman barons whose loyalty to the Angevin dynasty was consistent but contingent on the receipt of lucrative favours? 
Sentence (from "Ranulf de Blondeville, 6th Earl of Chester"): Ranulf de Blondeville, 6th Earl of Chester and 1st Earl of Lincoln (1170–1232), known in some references as the 4th Earl of Chester (in the second lineage of the title after the original family line was broken after the 2nd Earl), was one of the "old school" of Anglo-Norman barons whose loyalty to the Angevin dynasty was consistent but contingent on the receipt of lucrative favours.
