Morwen was a daughter of Baragund of the House of Bëor, and she married Húrin of the House of Marach. She was the mother of Túrin Turambar, Nienor Níniel and Lalaith.
Morwen means "Dark Maiden" in Sindarin (from môr = "darkness, dark, night" and gwenn = "maiden"). Her surname,
Eledhwen, means "Elf-maiden" (from edhel = "Elf" and gwenn = "maiden"), though Tolkien also translates it as "Elfsheen". Both definitions are in reference to her noble bearing.
