Terra Feminarum, described in Gesta Hammaburgensis Ecclesiae Pontificum (Deeds of Bishops of the Hamburg Church) by Adam of Bremen in 1075, is presumed to refer to the Finnic Kvenland, which at the time covered a part of the modern-day Finland.
Adam of Bremen relates in his work Gesta Hammaburgensis Ecclesiae Pontificum (Deeds of Bishops of the Hamburg Church) that his son Anund Emundsson died when leading a Swedish attack against Terra Feminarum and the attack ended in Swedish defeat.
No texts survive from this area, though the written text Vita Ansgari ("The life of Ansgar") by Rimbert (c. 865) describes the missionary work of Ansgar around 830 at Birka, and Gesta Hammaburgensis Ecclesiae Pontificum (Deeds of Bishops of the Hamburg Church) by Adam of Bremen in 1075 describes the archbishop Unni, who died at Birka in 936.
