Did Miriel see what was coming?

[Lord Elrond]

I agree with Sharku to an extent. She probably had some idea that the child she was bearing would be a very zealous person. Since Feanors body burst into flames and was blown about by the wind when he died who is to say exactly what Miriel suffered during the actual conception and delivery of him as well. Probably the same burning feeling that occurred at his death to say the least.
