Raegenald was succeeded by Sihtric (Sigtryggr, another grandson of I'varr), who married ZEthelstan's sister.
In 937 a great fleet and army were brought together by Constantine and Anlaf, the son of Sihtric, another Norwegian chieftain who had allied himself with the Scots, helped by Anlaf Godfreyson from Ireland.
Anlaf the son of Sihtric again came to England in 940 just after the death of lEthelstan.
One of Ethelstan's first public acts was to hold a conference at Tamworth with Sihtric, the Scandinavian king of Northumbria, and as a result Sihtric received Ethelstan's sister in marriage.
In the next year Sihtric died and Ethelstan took over the Northumbrian kingdom.
