ÃÂthelhelm or ÃÂþelhelm ( â ) was the elder of two known sons of ÃÂthelred I, King of Wessex from 865 to 871, and Queen Wulfthryth.
ÃÂthelred's sons were infants when their father died in 871, and the throne passed to their uncle, Alfred the Great. The only certain record of ÃÂthelhelm is as a beneficiary in Alfred's will in the mid 880s, and he probably died at some time in the next decade. Following Alfred's death in 899 ÃÂthelhelm's younger brother ÃÂthelwold unsuccessfully contested the succession.
Pauline Stafford identifies him with the ÃÂthelhelm who served as Ealdorman of Wiltshire, the probable father of ÃÂlfflæd, who became Edward the Elder's second wife about 899. However, Barbara Yorke rejects this idea, arguing that it does not appear to have been the practice for æthelings (princes of the royal dynasty who were eligible to be king) to become ealdormen, that a grant from Alfred to Ealdorman ÃÂthelhelm makes no reference to kinship between them, and that the hostile reception to King Eadwig's marriage to ÃÂlfgifu, his third cousin once removed, shows that a marriage between Edward and his first cousin once removed would have been forbidden as incestuous.
The historian ÃÂthelweard (died c. 998) claimed descent from King ÃÂthelred I and may therefore be a descendant of ÃÂthelhelm. Some genealogists have suggested that the Godwins descended from ÃÂthelred I through ÃÂthelhelm, but almost all historians dismiss this idea.
