[Isabel De Birkin.FTW]
The legitimacy of this lady is maintained from the circumst ances of her father having bestowed upon her the manor of D rayton, in free marriage, which the lawyers say could not b e granted to a bastard; but had she been legitimate, she wo uld surely have succeeded to the earldom before her aunt.
