Most impressive female character

[Lalaith]

I didn't say that she was the most impressive female, but she was impressive in some way. She raised her children alone (okay, many females do that), she sent away her son for his own saftey (that must have been hard) and then she followed him, although it was dangerous. She searched for him and didn't want to stay resting in Doriath. I think the love for her children must have been very strong.
