In 1264, with the collapse of Norwegian sovereignty along the western seaboard of Scotland, Alexander III, King of Scotland forced the submission of Magnús Óláfsson, King of Mann and the Isles.
[8] The following year, Magnús died without a legitimate heir, and his island realm was annexed by Alexander.
[12] Later in 1304, Aufrica quitclaimed these claimed rights to Simon de Montagu.
In 1305, the claims of a Maria, daughter of Rǫgnvaldr Óláfsson, King of Mann and the Isles, were pursued by her grandson, John Waldeboef.
[23] Although John de Courcy is not known to have had any legitimate children,[24] Aufrica's claim to Mann could indicate that she was a granddaughter of John and his wife, Affrica, daughter of Guðrøðr Óláfsson, King of Dublin and the Isles.
