 H. P. R. Finberg suggests that she was the Wynflæd who drew up a will, supposedly sometime in the mid-10th century, after Ælfgifu's death.This lady held many estates scattered across Wessex (in Somerset, Wiltshire, Berkshire, Oxfordshire, and Hampshire) and was well connected with the nunneries at Wilton and Shaftesbury, both of which were royal foundations.On that basis, a number of relatives have been proposed for Ælfgifu, including a sister called Æthelflæd, a brother called Eadmær, and a grandmother called Brihtwyn.
