According to Granville (12th century) marriage of an abducted _unwilling_ woman/girl could not be considered a valid marriage in common law. Note that this was not necessarily the same as the Civil law governing marriage as a sacrament. (One determined if the marriage was valid form the point of view of inheritance of land , mainly, the other from the point of view as to whether the co-habitation was sinful).
This also was often complicated by the mediaeval ideas around pre-contract .
Some time later (can't remember when, but I think around the 15th century, it was changed so that even if the woman were willing (to be abducted) it was still unlawful
But it appears Anglo-Saxon law may have been different
from The Laws of Ethelbert, King of the Kentish Men , 560-616 AD
If a man carry off a maiden by force, let him pay fifty shillings to the owner, and afterwards buy (the object of) his will of the owner.
