Earl David got married to Maud in 1190. She was also called Matilda (a form of Maud). In Munday's play, Maid Marian's real name was Matilda Fitz-Water. Maud was the gd-dau. of one Rannulf, Earl of Chester and sister to another Rannulf, Earl of Chester. When the later Ranulf died in 1232, Earl David's son John became both the earl of Huntingdon & Chester. This is important because the very 1st. literary reference we can find for Robin Hood ballads refers to the "rymes of Robyn hood and Randolf Earl of Chestre".Also there were blood ties between the earldoms of Huntingdon and Chester.
David was also a bro. of King William. The Lion, whose parents are: Henry Dunkeld De Huntington* and Adelaide 'Ada' De Warrene*.
This David Huntington (suspected of being Robin Hood) is my ancestor, from extensive research of genealogy.
