Ragnheiður Jónsdóttir (1646–1715) was a wealthy member of the powerful Svalbarðsætt family. She was married twice, each time to a Lutheran bishop of Hólar: Gísli Þorláksson (she was his third wife) and Einar Þorsteinsson.[1] She survived both husbands and retired in 1685 to the farm of Gröf in Höfðaströnd, just south of the modern-day village of Hofsós, appointing her younger brother Oddur as ráðsmaður (household manager).
