Thanks for the link, Mike.

I found that skimmming worked surprisingly well for The Lady Odivere. Anything rather than puzzle through all those unfamiliar words.
For example, if she says

"Athwart, thou scrant and ganely knaw,
Ye'll neer ha loof of me!"

I know she doesn't like him, even if I never know what scrant or ganely mean. Experience says that knaw is probably knave.   

I never did figure out what happened to the baby. Let me know, somebody.

Acc. to the editor, the backstory is that the maker of an Odin's oath gets his wish, then wishes he hadn't. This is the case with Sir Odivere, who married the proud and beautiful woman that all the other men wanted. Then she proved unfaithful, and he wanted to kill her.

In the usual way of people in myths, he co-operated in his own downfall by going off and leaving her alone for years.
