What is "aelfwaru"

Ælfwaru (died 27 February 1007) was an Anglo-Saxon noblewoman, who bequeathed her lands to churches such as Ely, and Ramsey. Chroniclers, writing in the 12th century, transcribed such bequests, from the original cyrographs. Ælfwaru's cyrograph has not survived. Ælfwaru's father, Æthelstan Mannessune, had two sons: Eadnoth, and Godric; and two daughters: Ælfwaru, and Ælfwyn.
